Just bought a Ruger 270 WSM with a 22" barrel, nice gun. Planning on shooting 140 gr SST's or BT's for deer and switch to the failsafe or Accubond should the need arise. Most of the data I've seen so far I4350 is putting up good numbers with 24" test barrels, question is with the 22" barrel should I consider a faster burning powder. I already know I've lost some speed with the shorter barrel, but for the 7 lb gun you have to trade something. I'm open to suggestions. Thanks, Rick
