300AI because of the freebore discrepancies, but NOT the stuff from the PO Ackley book. I have his books, and they could have been called " How to disassemble your rifle through the use of injudicious handloading" Crazy hot stuff in that manual. Actually, no real difference in what the two rounds should do which is why I said to get a batch of 7828SSC and work up unitl you get to 3200 w/180's or 3300 w/168's andcall it good. Might could go more, but no one can know for sure if the pressures are OK and then the question is..... WHY?

180 TTSX at 32000 does it all, unless a 375 or larger is needed. Easy as that. And to have this in a pre 64 model 70? Absolute perfection in hunting rifle nirvannah. Don't get no better than that.

LOVE God, LOVE your family, LOVE your country, LIKE guns and sports.
