that is what kimber uses on their .375s and .458lotts. if one gets the .458 bench recoil sled is a must that way one can fire it w/o taking it on shoulder and jaw. i suppose to do it right one would have to take recoil energy of 500grains starting out at 2300ft/sec on the shoulder. can you imagine taking that pumishment on your body? thank god for 2.5x leupold.
ps. at least that german gun came with target certificate indicating it was sighted in to shoot vollmantel slug of certain weight and make.
