A lightweight Win M70 .458 WM that was re-chambered to .458 Lott shooting 550gr Woodleighs, probably didn't weigh more than 7 pounds and with a small footprint that distributed the recoil onto a very small part of the shoulder. Brutal.

I have a CZ 550 I had re-chambered to .458 Lott which is not bad to shoot at all. That Winchester was almost unshootable.

My Ruger Blackhawk .45 Colt with 320 gr Keith bullets at 1,200 fps is also a handful and very unpleasant.
