For a plain 270 I have used IMR4350, IMR4831, H4831. Ramshot Hunter, Ramshot Magnum, and Rel 26. I have IMR4451 on hand to try, but have not yet.
My standard is 60.0gr H4831 over 130gr bullet. I have GMX, TSX, TTSX, and BT's always loaded up to try in any new to me 270. Going out tomorrow to shoot a donor Kimber Montana 8400 in 270 to see what it does with those four loads. Typically I will find one if not two loads that shoot very good.
