Re: Case head squaring
VH, and J Jones,
Let's suppose the action has been blueprinted. My friend's argument is that squaring a bolt face would especially help when squaring case heads. In other words, a square bolt is squared for straight cartridge alignment but it only works if the case is square. It is a two part system and both parts must be done to gain any benefit.
I kinda think that it is picking fly crap out of the pepper as I have seen many a small group without the cases being squared, but his theory does make good sense.
As far as how to do it, he turns his heads on a wilson trimmer that has been altered to trimming on both ends of the case. I have seen his setup only a few times, and I can't remember exactly how his trimmer has been altered, but I know that he ordered ALL the parts from Sinclair. I believe he is indexing off the Wilson case gages. Of course they only make those things in certain calibers so if you have a wildcat you probably can't do it. I would think that you would only be able to do this technique before your gunsmith threads on and headspaces your barrel or else your headspace would be off several thousandths.
Anyway, I'm curious what you think. [img]/ubbthreads/images/graemlins/wink.gif[/img]
If it's not far, it's boring.
