Well, lets talk some logic here, what is the actual recoil of a .50 BMG (without a muzzle break) ? somewhere between 150-180 ft-lbs ? (I dunno the numbers Im just estimating them)
Im guessing these numbers becuase the mighty .460 weatherby pushing a 450 grain bullet has about 7000 ft-lbs of energy with 100-ftlbs of recoil, but of course the muzzle break drops that by 60%, so your looking at about 40 ft-lbs of recoil (WITH A MUZZLE BREAK)....
a .50 BMG, even on a 30-lbs rifle, its GOT to have atleast 40-60 ft-lbs of energy (unless you load down your rounds), I mean, seriously a 40-60 ft-lbs of recoil energy might not sound alot, but thats 2-3 times the recoil of a typical 30-06..... thats still alot of recoil......
I dunno about you guys, If I had all the money in the world I still would never get a .50 BMG for hunting purposes, MAYBE 338 lapua, but not .50 bmg
