30 BR question, I read in here

[frank1947]

I read a post about 30BR, and load data for one with a 1/10 twist and a 150gr bullet, I guess I don't get around much but what would you use this far, I have a 30BR I love 1/17 twist for use in VFS, I think a 150 in maybe 1/12 or even 14 would be cool for a 150 or 155 , I can't remember what is palma twist? so anyway I love 30BR would like another interested in this 1/10 twist and I guess there is a special reamer for certain amount of freebore?

Frank, I got that 1:10 barrel in a trade, figured that I would play with it. The original owner who ordered it was planning on making subsonic loads for it I was told. He gave up after a 100-ish rounds and sold it to the gentleman who I traded with for it (whom never shot it). I have not mounted it as of right now, I am waiting on dies to arrive from Lee, didn't want to invest a lot on a possible experiment plus I have had good luck with the Lee Collet dies.

I don't know, I'll have to look into that and see what I can find out for ya. I am hoping a 155 A-max (or similar styled bullet) will fit without protruding into the case too much.
