452 custom barrel action

[grauhanen]

am I saying by using a specific chamber you can get the same results no but your chances are much better in having a rifle that shoots most ammo fairly well. again you just need to know what to look for.
you keep believing in the broad generalized beliefs without even knowing for yourself as in never trying a custom barreled rifle with different chambers.
I know and believe in the results I get. I posted to this thread because your statement to the OP is not completely true as I know for myself what can be done.

In this issue I'm not sure it matters what I do or don't shoot. Of course I could be wrong and a Lapua-specific chamber is the shortcut that will turn straw into gold.

To return to what you've said, it seems implicit that you contend that all lots of Lapua shoot well, and that if the OP uses a "Lapua chamber" with a custom barrel that will assure that he'll meet his goal. You may also be suggesting that using a Lapua-specific chamber obviates the need for lot testing.

I said that using a Lapua-specific chamber is not a "shortcut" that's going to produce the OP's desired consistent .25" reselts at 50 yards. To be sure, using an ammo-specific chamber can help, but is the chamber a guarantee of results, regardless of what lot of Lapua is used?

My experience with non-ammo specific match chambers is that not all lots of any variety of ammo will shoot equally well, including Lapua.

If your experience is that a Lapua-specific chamber turns all Lapua into gold, it would be astounding to learn of any serious shooters using anything else with Lapua ammo. Since Lapua is currently the most widely used ammo among BR shooters, are Lapua-specific chambers used by the majority?

If it is in fact the case that an ammo-specific chamber is a shortcut that works, I ought to get a Lapua-specific chamber in my next barrel.

Glenn,

Not to argue your point. Kevin has posted of about this. Testing rifles would be a fairer description. He receives a case (or two?) every year, and runs this through his various barrels/actions (possibly recrowning/chambering) until he finds one that works.

It's a hard life...

Tim, it sounds like you're suggesting Kevin Nevius doesn't lot test for the best ammo but instead barrel tests for the best barrel. In other words, it seems like you're saying he gets one or two lots (one lot per case) and tests many barrels to find which will shoot the one or two lots of ammo best.

While I don't know what Nevius or anyone else does, my impression was that, despite being a Lapua-sponsored shooter, he picks his ammo just like everyone else. When asked on another forum about his access to specific lots of Lapua with certain MVs by lot number, he replied "sponsored shooters have no preference [for lot speeds by lot number] - we pick from the same lots everyone else does, available at the time you happen to test." (See post #23 https://www.rimfireaccuracy.com/Forum/index.php?threads/lapua.29287/page-2 )

Glenn,

Exactly that. I'll dig out the reference later. It's quite possible that Kevin's practise has changed over time. Kevin does his own gunsmithing, and has several prone rifles.

My point was that even with a Lapua-specific chamber (his own), Kevin still matches ammo to a barrel. His competitors might wish otherwise....

I have a pair of 452's which I have done very well with shooting ARA factory class but as much as I love my 452's I would never build a unlimited rifle on a 452 action. When I want to go to unlimited I will go with a Turbo or a Stiller action.

Well, I never said it will make gold out of all and you even quoted me-am I saying by using a specific chamber you can get the same results no. I said shoots pretty good for me.
What I find interesting is you mention RFBR and what those shooters use, yet you don't even shoot RFBR so how can you even fathom what they use or don't use but that is typical of your posting, I come to learn with you for example-
if someone was to say I just painted that door black you would tell them it looks like a dark purple or even a very, very deep blue to me but not black at all no, it can't be black, black looks like this!

do yourself a favor and go chamber up some barrels however you want and see for yourself don't try and tell others what they can and cannot achieve without trying it for yourself first.

as they say you can read and quote poetry all you want but your not a poet until you write your first poem!

Lee, you may wax prosaic in favor of shortcuts, but let's leave it as you saying a Lapua chamber will be a big advantage, or something similar. I'll stick to what I said earlier: "There are no shortcuts, such as using a chamber "designed" for a particular variety of ammo."

Thanks for your thoughts guys. So I am in the process of ordering a barrel and needed the diameter of the barrel. I pulled the action and low and behold the barrel has a recoil lug machined into it. The action only has one screw, I forgot that little tidbit although I did see that when I bedded it. So I am thinking I will glue in the action when I get the new barrel and not play with the recoil at all, just leave it off. Does this sound reasonable?

I am going to bump this question as it ended up as last post on page one. Hoping for thoughts.

If you are determined to use this action, I would still stick with the threaded barrel and not glue it in. also maybe look and see if you can add another action screw.

[Gabe22BR]

I bedded my lug, tried to center it best I could, bedded the rear as well, and I made a pocket at the back tang fo bedded to set in.
I turned out some aluminum pillars for mine, and bedded everything together at one time..
Knowing Cooper 22’s are bedded 1” under the chamber area, I free floated my barrel..

Just the way I did mine…

No not glue the barrel in, glue the action in.

 

[Hi-NV Shooter]

No not glue the barrel in, glue the action in.

Ok that makes sense now.

Again, when people see a guy standing in front of an amusement park ride telling everyone walking by this is the greatest ride and they ask him how many times he has been on it and he tells them I haven't.
not surprising they keep walking. maybe it is time for him to try the ride to put more substance on what he says.

fact is Glenn, there are a lot of gunsmiths who use specific reamer/ chambers specs. when they chamber a barrel because they have learned from EXPERIENCE that just using any general reamer/chamber specs. will give hit and miss results.
call it a short cut whatever but this is fact not an assumption.

grauhanen, you wrote Lapua is currently the most widely used ammo among BR shooters. I think the statement is interesting. How was this determined? Thanks, Ron.​

I would say he is correct, at least among the ARA/PLS/IR50-50 shooters anyway.

I haven't disagreed with the idea that experience tells gunsmiths that certain chambers may be more helpful to accuracy than others.

Where we disagree is over my straightforward point that a certain chamber is not a guarantee of or a short cut to .25" groups.

Because you've been on the amusement park ride, you believe that having a certain chamber will move a shooter by leaps and bounds ahead of those who don't have it and that as far as the OP is concerned it is and will be the guarantor of .25" groups at 50.

Even though I haven't been on your ride and won't pejoratively characterize your posting as you have mine, I accept that you believe this. The discussion should end here.

If by no other means, it was determined by what the BR shooters themselves have said is being used. For example, widely recognized BR shooter Tony K. Harper said in November 2021 that by his estimate only two of the top twenty IR 50/50 shooters were using something other than Lapua.

See Harper's thread here http://benchrest.com/showthread.php?104498-Ammo&s=fcb641d06d1506d6ef0d0497e340e52f

As I said go find out for yourself and then come back and start speaking of it won't or can't work. but stating what is the obvious of there is no guarantee with anything is pointless. you have ZERO EXPERIENCE on what the OP was asking!
remember you started to twist my statements as being absolute. you provided no information to the OP in regard to his question of what he should expect if he replaced the barrel. it actually seemed like you were discouraging him to even do anything.
yeah, I been on the ride and when others ask me on how to get on it, I tell them, so far none have come back and told me they were disappointed a lot have thank me for sharing.

Butch, you should start making them again. there would be a big demand from ARA factory shooters. of course you would probably have to give up shooting with all the orders you would get!

Lee, they worked great, but it was a pain getting the bolt out. I sent a couple triggers and prints to a smith in Oz. I haven't followed up on them. I may have a few that have not been completed.
