I want to share two tips to help you get better results with the stripped bolt method of finding your touch point. The whole idea is to have a bolt close/open with no resistance so that when your seating the bullet deeper in the case the only thing causing any feel on the bolt is the bullet/land relationship. Any other interference will effect how the bolt feels. 2 common issues are runout and extractors. If you have runout in the dummy round the bullet will drag against the side of the freebore and skew the results. A concentrity gauge will tell you if this is a problem. Straighter the better. The other problem is extractors that apply side force on the base of the case. Defiance is a big one here, their mini16 cut is deep and will put side pressure on the case. I put a piece of tape on the bottom of the extractor to hold it up enough to eliminate that. Either of these two issues will cause you to never get rid of the slight click at the top of bolt lift.
