terminater was posting earlier talking about something else along those lines....the possability of reaming .270win out to AI as guys wank on and on and on and on about how much better the .280AI is so I ask why not do it to .270????
for what its worth I chuck 170 grn projectiles through my stock std short soda straw thin barreled mod 70 .270 with no issues at all,they group sub moa when I do my bit and hit like hammer of thor. my load data runs in perfectly straight line from 130grn-150grn-170grn ADI list loads for barnes 180grn pill so that will/may also give you hint as to good starting point.
