I have had a model 12 bvss for many years now in .223. I have always had quite a bit of cratering on my spent primers. Most of the time the primer edges were not flat, so I new that pressures were good.
I was considering a bush job, but felt that these bolt heads may do the fix.
The new bolt head works great !! I am very happy with the way my primers look now. No more cratering issues !!!
I did have to re headspace, but that was not a big deal, and should actually help my brass last longer. The factory headspace had to be .01-.012. I set mine around .004-.005 now.
Just thought I would pass this along.
