I've shot a bolt 50 BMG without a muzzle break on a Mauser magnum action. It wasn't the worst. Maybe because I was holding her tight, and the rifle was heavy.
I think shooting a double 3" Magnum in a light double barrel might have been the worst. Maybe because I wasn't expecting both barrels to go off simultaneously
My 416 Rigby Ruger 77's stock did not fit me well. It caused headaches rather quickly; I was shooting close to 416 Weatherby power loads in it though (no muzzle break).
The friend who had the 50 BMG also had a 460 Weatherby, especially ordered without a muzzle break, shooting heavy loads in that wasn't something I'd like to do all day.


I prefer classic.
