I'm hoping someone skilled in this matter can help. 50/55 grain bullet,Probably one of Barts 52 grain Flat base. Here's what I'm thinking
Lapua brass.JGS reamer .247 neck , turn necks to .010. -0- freebore, going to make the neck shoulder junction a .062 (r) as opposed to .125 in hopes of slowing case growth. Its the particulars like lead angle, throat OD, and any thing else you could think of . thanks in advance for you ideas. Bruce
 
make up a dummy round with 50-80 thou in the case with the barts 52, and spec the throat there. case volume is a plus
