Lone Star,
Was that data taken from Sierra's pistol data, or rifle data? I don't have their newest edition and the 270 isn't in the pistol data of my older books.
I've been shooting 45 grains of IMR-4895 with a Sierra 90 gr HP and getting consistent groups of 1" or better at 50 yards. :grin: That's good enough for me considering the trigger, gotta take it apart and try to get rid of the creep.
By the way, what powder are they recommending for the 90 ?
Thanks, ~~ raynor
