I ran a 130 Berger CH at 3089 fps at 7500 ft 40 degrees 25% RH and a 23.0 baro. What it was the last time I was in WY last fall. Just ran it again. Its correct. AB dont lieThere is no way your numbers for the 270 wsm are correct .
I run your velocity at altitude on my app and have numbers no where close to what your claiming with your load !!
I get 1753 FPS and 887ft/lb at 1000yards with your load.
What your saying you get with your load beats my 270 wby shooting 140 classic hunters @ 3390 FPS not likely
