New Sniper Rifle!! PICS

I have a tactical buffalo thumper too! It's in .375H&H almost identical to yours but wearing a leupold 3-9 vx-r. I shot my buffalo with a 235gr tsx, I recovered the bullet, it weighed 235 grains and looked like a perfect mushroom that expanded to .82 at its widest point. It penetrated the ribs passed through the heart and was found between the ribs and hide on the opposite side.
 
How hard do those things kick? Seams like it would be atrocious but I never hear any complaints. No muzzle brakes either

My .458 win mag kicks, 500gr bullet at 2050fps, not exactly pleasant on the shoulder and the hard rubber recoil pad although it looks nice doesn't give much for comfort. 400gr rounds that aren't that bad. The 375H&H isnt bad
