My single barrel turkey gun is the hardest kicking gun I`ve ever shot, bar none. My 270 kicks less than a 223.
Some guns it just don't matter...I always get a kick out of folks attempting to shoot big bore rifles on the bench at ranges. If you want to shoot the big bores (338+), take it off the bench and shoot standing and off sticks. Let the body recoil back to absorb some of that punishment you requested.
Is it a Mossberg 835? Those things are brutal to shoot.
You don't hear about an 8mm rem mag much anymore. Beast of a cartridgeOf the rifles I own it would have to be my 700 BDL in 8mm Rem Mag.
Amazing how it takes more recoil to kill a 20 pound bird than to kill a 10k pound elephant.3.5' 12 GA has more recoil than Win Mag 458!
