I was wondering if you all could give me an idea of what to expect the case length to be if it started out at 2.720" on the virgin 338 Lapua case then necked it down to 30 cal and formed it with .018" total body taper using a 35 degree shoulder and a .270" long neck? At least I want a .270" neck left when I'm done. I figured it would come down to 2.7" from 2.72" loosing .020" and was about to spec and order the reamer at 2.72" but Dave Kiff at Pacific Tool warned me that some guys have been telling him they had up to .070" - .100" reduction in length when improving the 338 Lapua case, leaving them with very little neck at all. This doesn't seem right comparing the 2.7" case length that some have posted for the Yogi, so I'm kind of holding off for a day or two to order the reamer until I get this worked out based on the input I get. It's a tight neck, .333", so I want enough length to the chamber to fire form and not have to worry about it being too long on the other hand. Any experience or suggestions for a chamber OAL, brass length, etc would be very helpfull right now, thanks in advance.
