300WSM reamer spec.

With minimium but 100% clean out of Norma brass neck + Berger 215 Hybrid, which neck size reamer and leade angle should I purchase? Thanks.
 
I shoot 230 Hybrids with a .280" freebore and Ø.337" neck for .012" case neck. I recommend .200-.210" freebore and .339-.340" neck for 215 Hybrids with .013" case neck thickness. My Norma brass is fully turned at .013" case neck. Regardless any other factor, use a 1.5° leade angle.
 
Thanks Steve, if I want to shoot the 230 Hybrid, would it work with the reamer spec for 215 Hybrid? Alternately, would the .280 free bore work for the 215 Hybrid or may be a .240 free bore might work for both 215 and 230 Hybrid? Leade angle of 1.5° to reduce pressure? Please advice.
 
Erik Cortina used my reamer to chamber a barrel for 215 Hybrids and it seems to work fine. .240-.250" would probably work for both. I'm a little gun shy (forgive the pun) about hitting the doughnut, so stay away from it. The 1.5° leade angle is standard for many cartridges and has proven to be accurate over the years. When in doubt, send an email to Dave Kiff and he will help.
