Same here, I use a 3 inch shotgun patch over a bore mop.Have you seen the video of Speedy cleaning where he shows to put something like a big shotgun patch over a brush to dry out the chamber as last step?
I put the patch over a bore mop.
Me too, those shotgun patches are cheap and work well. I may even use a little brake cleaner on them now and then.Same here, I use a 3 inch shotgun patch over a bore mop.
All the way upso is this a tight bolt handle all the way up or just at the top during primary extraction?
What is the OD of the neck of your fired brass versus the OD of the neck of a loaded round?
I’m not sure, I will check and post back when I load my next batch. Hopefully this week and I can try some of these suggestions next week at the rangeWhat is the OD of the neck of your fired brass versus the OD of the neck of a loaded round?
You are using good components and when I initially read your post I immediately thought you were using Alpha brass since it tends to show heavy bolt lift prematurely.Hello everyone, I’ve done a lot of reading on this forum, but this is my first post.
I recently had a 6 BRA built with an Impact precision action and Krieger barrel.
The gun shoots great so far, but I’m getting a pretty heavy bolt lift, even with loads that would be considered light… I’ve been ladder testing loads between 29.6 - 30.5 H4895, which is giving me muzzle velocities from 2760-2880 with a 105 Berger hybrid. The bolt lift always seems to be heavy, maybe a little more with the hotter loads but not significantly.
I’m shootings Lapua brass, which I did fire form, but I really didn’t pay too much attention to the bolt lift when fire forming.
At the moment I don’t know the reamer spec that was used to chamber the barrel.
Other than the bolt lift there doesn’t look to be any other signs of over pressure.
Any suggestions for me!??
Thanks!
Not hard to close, nothing more noticeable than my other rifles.How much effort is required to close the bolt? Is the bolt closing freely? As in close with no effort required.
I guess that is possible, I’m using an LE Wilson 6BRA die, I haven’t heard too many bad things about Wilson dies..My first guess is the die isn't sizing the bottom portion of the brass enough or possibly at all. If so, a different die will help or, there's not a thing wrong with having the chamber polished out a few tenths either.
I use that same die with a chamber cut with a standard PTG 6BRA and Peterson brass with no issuesI guess that is possible, I’m using an LE Wilson 6BRA die, I haven’t heard too many bad things about Wilson dies..
How many firings on the brass? Like Mike I'm leaning towards a clearance issue somewhere. There has to be room for brass to expand enough and then snap back. That can be at the base as well as the shoulder bump. Getting brass into the chamber is one thing but it doesn't always mean that all is good after firing.I guess that is possible, I’m using an LE Wilson 6BRA die, I haven’t heard too many bad things about Wilson dies..
