It is really funny with recoil, about 25 years ago and friend let me shoot his .458 American, I fired one shot and that was it for me, shoulder swole up, I never wanted to shoot that again, now I routinely shoot 45/70 with max loads and 50 BMG, last time I had the 50 out shot about 20 rounds and loved it. Most of the rifles I have today are big bore, recoil sure doesn't bother me so much any more
And I bet that 50 you have has a brake on it? Brakes on big rifles do amazing work.
