Reloading Berger 215's & H1000 starting point?

Yes A big difference in freebore. BROZ told me to get a extra 50 thou of freebore compared to their normal TAC reamer. This is what I ended up with from PTG.

A very informative thread. The performance at 3000 fps is big vs my 2800. The headspace makes sense.

Ok guys you need to educate this old man a little bit about these reamers. I assume that you can ream chambers with the neck portion to various dimensions ie brass neck thicknesses correct?? Weight sorting brass relates also to case wall thickness which in turn relates to powder capacity right??The free bore is your jump to lands. Am I getting somewhere. This is all revalent to volosity and COAL correct??

Do you think 20 rounds is good for barrel break in?
