[QUOTE="royinidaho, post: 195069, member: 2011"] 270 AM 150 gr Ballistic tips or Accubonds > 3500 FPS. (I stopped at 3500) 169.5 gr Wildcat RBBT bullet (.7+ BC) 3200 FPS (Again I stopped at 3200) 195 gr Wildcat RBBT - BC out of sight high - >3000 FPS I had powder bridging problems with stick powders w/the 150s. I wouldn't even attempt a stick powder w/the heavier bullets. I use US-869 exclusively. 101 gr for the 150s. 95.6gr for the 169 and 93 for the 195s. If considering a 270 AM check w/Kirby regarding interior barrel design. If I were doing the 270 again I'd go with the 277 AM. Its based on the 338 Lapua case. Much, much better brass. Nosler is not nearly as good as Remington in my experience in the 270 AM cartridge. [/QUOTE]
