While turning necks on 20 VarTarg brass, that had been formed from once fired Lake City brass , this evening, I encountered a few that had quit a bit of wobble when chucked up. I am using a 21st Century case holder on a variable speed DC motor that runs true. I actually had no problem turning the necks as I "go with the flow" (wobble) and lightly hold the turner. I got to wondering why some of them wobbled, I took a close look at the few offenders and noticed that the rim of the wobblers had a high spot at one point. Probably due to a hard extraction would be my guess. I lapped the base of the case on a surface plate with 800 grit paper and it really showed up the high area. So much for why they wobble……..Now I am wondering how the uneven pressure from the high spot against the bolt face might effect accuracy when fired. Any ideas or comments? I sure hope this hasn't already been brought up before.
Thanks for any comments,
