Is bolt-action receiver blueprinting still a common thing?

The advent of “stacked tolerances” can rear it’s ugly head pretty quick.
I think where many actions and the machining goes wrong is at ~12:30 in the video. That's the point the action body is setup for machining the front end. Threading, facing and lug abutments. It's up to the operator to check and make sure the blank is in the machine true, if it's not there's trouble. I've had them where this was obvously not done correctly.

Edit: I certainly am not pointing my finger at BAT. Just a general statement towards the processes the manufactures go through.
 
If steel didnt warp when you machine it
I had a conversation with John Pierce years ago about this. At the time he said he had a harder time keeping the stainless bodies straight because of warping and the cro-moly actions did far better. That was the reason at the time he shifted to cro-moly only or mostly cro-moly (so long ago I can't remember all of the details). Probably where stress relieving methods and technique come into play.
 
How do you guys think the current Bat igniter or Zermatt Origins are coming out? That's what I am thinking of building on. It would be my first custom build. I do not plan on trying to compete at any real serious level. I may do some local casual competitions, but mainly, I want to learn to read the wind as my goal for the next 2 years. I figure all I need is 1/2 moa while I learn this game, but after that... how far can the igniter or origin take me?

Little bit of info here,


Same action from the post below in the video.
 
I think the term improved would be better than trued. And I still can't get my mind around working on a banana basically with equipment that would struggle to hold tolerance on a pool cue as some guys claim to accomplish . With all this work it is still lip stick on a pig . Flame suit on ! LOL
 
"Blueprint" could mean different things to different people. Does it mean correcting/adjusting bolt timing? I'd guess that most guys like me who can run a machine might face, fix threads, and lugs... but I'm not touching the timing... which just got worse because I fiddled with things that effect it...

side note... as much as I don't like bedding, I love it. It's the last step to making a rifle!
When a smith takes metal off of the front of the lug abutments, and off of the backs of the lugs, as part of the truing process, that sets the bolt further back in the action body, and that will reduce or eliminate extraction, in terms of the length of pull that the extraction cam produces. Doing all of the other work and not fixing this seems to me to be an incomplete job. For those who are not up to doing the work needed to fix this, there is a specialist who charges a fair rate, and is very experienced. http://accu-tig.com/
There are fixtures, either commercial products, or smith made that are routinely used for this work. As I understand it the idea is to have the gap a the front of the root of the bolt handle, between it and the front of the bolt notch, be correct, and the rotation timing such that the end of the strap of a 700 bolt lined up with the side of the lug. This alignment and the location of the detent at the top of the cocking cam put the cocking piece in its correct position so that it runs down the center of the notch in the bottom of the action.

One thing that I see that is to my mind incorrect is commonly seen in videos on this subject where the bolt is rotated showing a supposed lack of extraction when what is being seen is simply the tension of the striker spring causing the lugs to follow the closing cams. Without a tight fired case in the chamber with the extractor engaged to prevent this, I do not see how this can be properly evaluated other than just knowing what the proper gap needs to be at the front of the bolt root, with the bolt closed.
 
Or do most shooters just buy a top-shelf receiver like a BAT, Defiance, ARC etc, that comes blueprinted already?

I'm just getting a feeler because I am thinking of taking Gordy Gritter's blueprinting class ($1,600) and buying the tools and jigs (another $1,200) so I can offer blueprinting services.

I'm probably going to buy a Rem-700 receiver soon to blueprint it and do a full build for myself. I'd just hate to invest all that cash for services that aren't in demand.

Thanks for your opinions.

Tony.
What a loaded question. Do you have a lot of extra money on hand that you will not miss? Does price versus performance matter? Do you mind unsecured debt aka credit debt? Are you a super consumer that actual believes stupid nonfactual marketing like the idea of "You get what you pay for?" which did not exist as an idea prior to post WWII marketing/advertising?

Yes plenty of people purchase factory mass produced actions and get them blue printed depending on the what you intend to use the action for. Your custom action makers in their wildest dreams could not supply all of the action needed at the competition level int he USA let alone globally!

No one that sells custom actions especially to PRS, F, Silhouette, NRA High Power etc....Can or will actually tell you specifically what levels of concentricity, runout, clearances, tolerance stacking you get or do not get for the money. None of them give you any guarantee's of any kind on the machine work or accuracy of the product. They do not give you lock times or anything like that. They do not use high end materials not used by OEM mass produced actions over all. A lot of them are using cheap built up bolts from sub assemblies and are using floating bolt heads like a Savage or Thompson. A lot of them do not give you a trigger included, bottom metal, magazines in the base price.

If I am going to spend 3X+ for a custom action I want to be able to check what I am getting against the print so I know I am getting everything I have paid for. I want a guarantee of performance! If I have to send it out to a machinist or gunsmith to check it out than I have already lost. If I have to have a custom action blueprinted and you will find people on all of these shooting sights that do just that than I have already lost. If my machinist / gunsmith has to do anything to it I have already lost!

Price means nothing to me if I can not measure it than it is not real! Rifle actions are not high fashion in spite of how girly most men in the shooting sports have gotten!

So I am not against custom actions I just think they are marketed like womens hand bags and shoes and that machines should be sold on things that can be measured especially if they are supposed to be more precise and accurate. I do not want marketing hype adjective and adverbs I want things that I can measure. Words are cheap!

I want to know what prefit barrel and what weight and brand ammo I need to assemble and use to get the guaranteed accuracy. It had better be at least a 1/8 MOA group to be worth the higher price point out of the box with out the need of a gunsmith. It should be plug and play buy these parts put together your self use this ammo and you will get this result. If you have to send your 3X+ expensive action to Gre-Tan or someone like him to assemble the parts at a high cost than what did you get for you money? Not much!

Instead you get bromance soft sells where a guy get's a Terminus action and just vomits praise for it with lots of words with out actual saying anything of value like a politician so lots of words and praise but nothing of meaning or value actual said. I want to thank my sponsors blah blah blah.....I could not have done it with out Terminus, Hornady Ammo, NightForce blah blah blah even though that guy was not running that gear when he first made it to nationals etc....but now he could not have done it with out them etc.....HE got those sponsors while running a blueprinted Savage and Sightron Scope and Brux barrel but now that he is getting free gear, discounted gear, and a some form of financial incentive he could not get to where he got without the new gear paying the bills!

It is disingenuous. We all want to get paid but lying to people once you have made it just to get paid is cheap and trashy.

None of these custom makers will put their products especially if purchased with out their knowledge up against a variety of factory actions that have been custom machined by SSS or Gre-Tan or similar high level gunsmiths/machinists. None of these gunsmiths would ever put out a spreadsheet of the numbers they have measured pre and post machining by brand out of fear of litigation.

So at the end of the day no one on this site or any sight can tell you anything other than observations with insanely small sample sizes and nothing that can be measured out of fear or because it would hurt their cash cow.

So if you want a custom action definitely get it but do not fool yourself or try to impress others with an action you know nothing of importance about outside of the financial cost. The only critical number you know is the price point. LOL

If you actual dig a little bit one of the cheapest action designs the Savage 110/10 action has produced a lot of wins and records outside of BR shooting. I will admit the Savage actions are a terrible design but the import parts are all there and they are easy to blueprint and produce fantastic results with just decent machine work. SSS has plenty of people racking up wins at high levels with Savage actions. The US Army, FBI, Secret Service and the Marine Corp. have done some fantastic work with Remington 700's again not the best design or execution but after basic machine work and a match grade barrel pretty good!

So what ever you decide to do just make sure you do it because that is what you want and not because some idiot like me on the internet talked you into something with zero empirical and quantifiable repeatable evidence that can be measured. Question anyone and everyone and the more of your time, money, brain, heart or soul they want the more you should doubt them and the more you should demand of them!

Almost no one on the top of the food chain started out with the high end toys they are playing with today!

Nothing trumps practice which means ammo, components and a place to practices.


Nothing is more important than a mentor to teach you how to read the wind and how to do precision reloading. If you want to short cut the learning curve get a mentor that has already done what you want to do! So you do not have to learn from trial and error! Sadly since that can not be bought or sold it is the thing no one pushes on any of these sights!
 
I took Gordy's week-long class and asked him the same question. I think you'd be surprised how many people just want to improve a hunting rifle that only gets a few shots a year... or a gun that has some sentimental value and gets small incremental upgrades.

Knowing how to blueprint gives you the knowledge to check and measure the allegedly "blueprinted" custom actions. You'd also be surprised how many aren't perfect.


I don't think you need 1200 dollars in tools? You've got a lathe... you can make a lot of them.
Yes Yes Yes!!!
 
Clearly, some need to change the brand of cigarettes they're smoking '. :D
Cheap shots are just that. Let's assassinate the messenger becasue we are super consumers and do not want to examine ourselves at all. Not funny at all it is no different than CNN's cheap shots against though that speak the truth they do not want to hear and that opposes their own message!
 
Quite a few years ago, over on BenchrestCentral, a shooter was commenting how a VERY well known Gunsmith “trued” his new Stolle Panda.

It took the people at Kelbly about a minute to get on line and tell him he wasted his money. They also demanded that the Gunsmith cease messing with their actions, as they were correct out of the box and required no fixing.

It was a pretty lively discussion.
Bake that up with some sort of provable facts? Names, contact info, measurements of the key dimensions of the action pre and post machine work?

You might as bell have said "My friend Buba was working his way through a case of Bud Light while fishing in the Chattahoochee when he say a UFO and the UFO told him to stop drinking Bud Light!". That is how nonsensical that and irrelevant that sort of info is if it can not be corroborated.

I would agree though that what is the point of spending all that money on a custom action if it still needs machine work!
 
If you do find something wrong with a custom action, my experience is they will fix or replace it.
How do you exactly find that if they have not given you specifications or guarantee's of run out and the like?

How do you find this unless you have a competent machinist check the action? At this point what was the point of spending big $$$$ on the custom action?
 
In this case it makes sense. Giving someone a reason to be happy is a good thing.

In the case of the Stiller Predator I have, Jerry made other improvements which you would not be able to implement if you started with a 700 action.
Yes I understand this to be true there will always be bad designs, better designs and great designs. Likewise there will be differing levels of execution with regard to how close to the blueprint a given manufacture get's!

You can always fix some issues of poor execution with in reason but you can not magically make a poor design into a great design!
 
Alex, it's people like yourself and others here that illustrate the difference between a craftsman and an assembler.

As far as out-of-spec custom actions goes, Randy Robinett and I both owned the poster child for bad actions. It took a lot of work from a savvy craftsman....and more $ than it originally cost...to bring it back from a date with the chop saw (quite literally) and turn it into a tournament winner.

Good shootin' :) -Al
I notice you do not list the action by name, what was wrong, what it cost to purchase or what it cost to fix.

This is the exact nonsense I am talking about. No one in the know will ever name name.

This is why I think this entire industry of gunsmiths and machinist are cowards! This is why this nonsense keeps happening over and over again.

I believe you are telling the truth but not enough truth to actual help anyone which is why I tend to think all custom action makers are liars and carpet bagers and the people that push them and sell them are complicit! Never anything that can be used to nail down anything like a standard!

No one can prove me wrong because no one that knows anything will ever say anything of value! It is all Hersey. If we ever wanted to get to the truth we would have to sue everyone or do like the French Revolution did and start getting necks ready for reconing(sp).

How is the average person ever going to know if their fancy looking expensive custom action was worth the price or simply window dressing?
 
All of this conversation makes me so nervous buying even a custom action. No way I could figure out if any of these were issues on something I buy.

I'm suffering from analysis paralysis! I don't know where to put my money for my first build now.
My point exactly. You can not trust the person selling you something to be honest or to educate you on what is best. They will always slant any true engineering with marketing nonsense when solid proven engineering does not support their design!

They make you absolutely no promises or guarantees that are empirical that can be measured. It is all pay me big money because I say my widget is better! No Thanks!

If I bought a custom action I would want every parameter measured and I would then compare it to my custom Mauser's, Winchester's, Savages etc.....I would then post my specific measurements! That said I should not have to do that. That is what bother's me. For the huge delta in price nothing should leave a custom action maker with out being checked over and over again. They should screw a barrel on and test fire it with their pet load to make sure it is a shooter before it ever reaches me!
 
Well, don’t loose too much sleep over it. Every piece of machine work performed has a tolerance, True, some tolerances are greater than others, but the brutal truth is, the tolerances are engineered to be acceptable within the perimeters of the application of the part being machined.

There are several videos on line where manufacturers take you through each step in the machining of a new action. Bat has an excellent one.

As a Machinist, I can spot flaws in a set up and how that flaw can result in parts being Machined. Where most inaccuracies occur is when the part has to be removed from a set up and re set to perform other functions. The Machinist, programmer, or operated must be sure that the prior machined surfaces are running as close to the spindle centerline as possible so all subsequent operations produce fits that are truly sytaight and square.

This sounds easy, especially in the modern world of CAD/CAM machining. But trust me, it is not as easy as it sounds. The advent of “stacked tolerances” can rear it’s ugly head pretty quick.

here is that video. A lot of great info here.

Prove it! A lot of supposition but not much substance. My processed meat spread is better than your processed meat spread because I said! LOL
 
In this day and age only the best methods should be used and not the cheapest methods if you are going to pay top dollar.

If a company is going to build a bolt assembly from small parts like Savage or Thompson or modern WInchester or Browning instead of one piece forging like a Mauser why should you pay a premium? Bolts with braced on bolt lugs, pined lugs, separate floating bolt head from the bolt body are CHEAP cost saving designs and not a sign of quality or engineering excellence. A custom action should be about the best of the best in every part not compromised for cost savings!
 
I am not a machinist but I prior to deciding to become an automotive Technician in Germany I did tool and die.

My wife is trained as a machinist but developed allergies to various cutting fluids.

I have an uncle that was a machinist in defense industry in aviation in Californian, Washington, Oregon I think Utah he developed dementia at a pretty young age likely due to exposure to chemicals in the industry. His son also a machinist in aviation industry just got a new Kidney at 40 again chemicals from industry. I have seen huge issue with health in aviation and automotive industry in manufacturing due to using cutting fluid additives beyond what is recommended to extend tool life cause MILES , ACRES of black mold in plants!

I have seen everything from 1940's technology to cutting edge technology since late 1980's until now.

I am not saying any of this to disparage anyone just that if you have never been in manufacturing and have not spent time doing precision machining or engineering parts and specifying the materials, the process and the tooling it is hard for the average consumer to have any clue what they are paying for.

A lot of people seems to think hand lapping a barrel is a sign of quality but it is the opposite of precision machining. It is an ancient technique that is needed to make up for the lack of precision machining. Precision honing on the other hand is a truly modern technique that is far superior to hand lapping in every single way. Hand lapping is like the use of feeler gauges it is the best we have but if 10,000 guys set valve clearance on a hot engine you will get 10,000 slightly different valve adjustments. Will it be within specifications? For the most part yes! Does that equal the finniest in precision or consistency or just the practical best we can expect and sufficiently lax standards?

If the standard is low enough or there is no standard that how do you fail? How do you evaluate?
 
I have a BAT MB that I want gone over to ensure I'm the limiting factor on my next BR rifle. Who is my guy?
