What is the largest that I can open the bolt face up. The action is l/a remington. Can it be opened up .600,.625,.650.675 safley? I know the bolt is .700, but how much is too much? I am working on a unique progect [img]/ubbthreads/images/graemlins/wink.gif[/img].

I talked for a while with the guy from CH4D about our dies. He suggested why not try and hit as many calibers as possible throughout the forming dies while ending at 308. I'll talk to you at work today.

OK Dave. I was hoping that kirby or shawn or maybe chris would give me some insight on what the max we could open the boltface up.

I open them up to 0.590" for Lapuas all the time. Don't know about going any further than that.

Chris

How exactly do you go about opening up the bolt face? Do you then install a Sako style extractor, or M16 style?
Please list in detail your operations and set-ups. I have a couple of bolts here that I bought off ebay that I'd like to give it a try on.
I am a machinist myself so I think I can do it just need guidence.
Thanks in advance
Dave

Dave are you asking for industry secrets? [img]/ubbthreads/images/graemlins/shocked.gif[/img] You might get both of us banned for that [img]/ubbthreads/images/graemlins/crazy.gif[/img]
