gre-tan bolt work

[Eric Leonard]

had a 700 done in 6.5x47L and pierced primers from the start,,sent bolt to Greg and got back in 2 weeks and like what I see,,will check back in a couple days after I shoot it but it looks better than my Stiller,,may have it done also,,

 

[Boxcar77]

Very nice work! I'll be watching for results, having a 700 chambered in 6.5x47 also. While not piercing primers they are cratered.

 

[Scott Harris]

Greg IS the man.

 

[timeout]

It will work perfect.

Greg did a Savage target action bolt for me a few years ago, also a 6.5x47Lapua. I sent it out on a Friday and had it back the following Thursday. Excellent service and beautiful work.

I would recommend him to anyone needing such service.

 

[Toolbreaker]

Add me to Greg's list, also. He took the cringe factor out of my load development

 

[jnyfeler]

I send all my bolts to Greg for this procedure.

Several years ago I got an early Stiller TAC30 (s/n #0004 or so) and the Kiff bolt had a big enough firing pin hole that I was cratering primers with factory BH 175 match ammo, much less reloads. Sent it off to Gre-Tan and got it fixed up. Next in line was my 40X in 6BR... several of my factory Savage Target actions have taken the trip as well.

A few years before that I had re-barreled a Savage 10FP to 6BR with a 27" Douglas 1-8" twist tube that shot great, but ran into pressure signs (specifically cratered primers) before I hit 2700fps. Luckily it shot awesome at about 2670-2680fps. At the time lots of people were claiming 2800-2900 fps from plain 6 BRs from 30" tubes, and Jackie Schmidt's barrel length vs. MV loss test showed something on the order of 8fps btwn 30 and 26"... I was completely baffled as to why I was hitting the wall so much lower. Some folks with custom actions told me that it was because I had a factory action. At the time I thought that was complete horse-crap - how the blazes would the bullet know the difference as far as pressure? They couldn't articulate as to *why* that might be true, and I just wrote it off as custom-action snobbery towards a Salvage... but later, after my experiences with getting the firing pin hole bushed on a number of factory and semi-custom actions (the TAC30 and 40x falling in that category in my view) I think I might understand what they were trying to say. Kinda wish I still had that particular barrel back again to test the theory on.

One of the best things I ever did for my 700/308 was send the bolt to Greg. I had big time cratered primers even with powder puff loads which made load development very difficult. Sent the bolt to Greg and had it back in record time and it was beautiful! I highly recommend Greg. You will be very happy with the result.

Greg does amazing work. I had my first bolt done in early 2000 something. He cured all the primer problems with my first 6BR and he has worked on a number of my actions ever since. I highly recommend this procedure.

 

[watercam]

He did a Winchester bolt for me and I NOT find the edge of the bushing. Don't forget he is just as good at all other aspects of building accurate rifles! Sending him my next barreling job.

Just finished my sixth and seventh. Bye Bye cratered primers. You would think Remington would have figured out by now their firing pin setup is junk but obviously they don't care.

I don't think its a matter of "don't care", as Savage and other factory brands suffer the same problem. The firing pin holes are made to a given dimension, with plus or minus tolerance. The firing pins are made to a given dimension, plus or minus a tolerance. The biggest firing pin has to fit through the smallest hole, and sometimes we get (un)lucky and get the smallest pin / biggest hole combination - and the primers crater like crazy. They can't take the time to hold the same level of precision machining as a custom action, and still make money. The factory actions are generally built with factory ammo, and SAAMI pressures in mind. Custom actions... I would presume are built with reloads in mind, and we all know 'some other guy' whose loads are just crazy hot :

They're using CNC machinery. It doesn't take any more time to make a hole .062 than it does to make it .070. Same with the firing pins. As far as SAAMI, they're about fifty years behind the times when it comes to tolerances capable of being held today by modern metalworking machinery. It's the reason there is such a boom in custom barrels, actions, triggers and Remington action/bolt rework. The SAAMI cabal wants cheap, not good and Remington's part of SAAMI.

 

[memilanuk]

Bottom line, all the new parts have to fit interchange with the old parts, or someone will have troubles and be burning up the phone to their lawyer. So the dimensional tolerances stay as they were.

 

[signut]

Have had two done, both were piercing primers, that stopped after Greg did the bolts.

GT is the very best at bolt bushing. I know he has been doing that work since the late 90s. His work is superb and allows you to establish great loads at a higher node, which is nice.

I'm glad I stumbled onto this. My last 25.06 build was cratering primers about 1.5 grs. below book max. After fiddling around with primers and powder I just figured, oh well. I have got to call them in the morning!

 

[butchlambert]

All of my Stillers had .062 firing pins. Never a problem and 3 were his earliest. Never had a problem. Why didn't you send it back?

 

[Eric Leonard]

I rebarreled the Stiller to 6 BRDX,,then had the 6.5 barrel fitted to a Rem 700 action with factory 308 bolt and firing pin,,
