i agree with James B that info for this caliber is hard to come by.
if you contact SSK industries they might send you there reloading data ,they did for me.
i have found that R15 and Speer 235 gr work very well ,using 54 gr of power , velocity is over 2200 fps.
my second choice is a Sierra 250 gr sbt
the info that i got from SSK shows a 270 hornaday RN with 52gr ofRE 15
the velocity they show is 2128 fps.
the recoil is on the severer side ,i hope you have the rubber grip,i cant even imagine why any one would want to use the wood grip. other than that ,hold on and don't let it go off untill your ready.
