8 twist wasn't fast enough for the 156 for me. Berger's stability calculator said it would be sacrificing bc at lower elevation and colder temps. That was exactly what I experienced. It made calculating my drop accurately too difficult. If I was only shooting in warmer temperatures and or higher elevation I probably could have went with it but practicing at lower elevation and hunting in the mountains didn't work out well. First round impacts were a guessing game. Going back to 140 hvld.
