Like he said. Found this:

The .577 Tyrannosaur or .577 T-rex is a rifle cartridge developed by A-Square in 1993 for big game hunting in Africa. The .577 contains a .585-inch diameter, 750-grain Monolithic Solid Projectile which when fired moves at 2,460 ft/s, producing 10,180 foot-pounds of muzzle energy. The production model from A-square is based on their Hannibal rifle platform. This cartridge has the distinction of possessing the heaviest free recoil of all commercially available, shoulder-fired weapons, at 220 lbs into the shoulder with its heaviest solid of 750 grains. The larger caliber, 700 Nitro Express, drives a 1,000 grain solid at 8,900 foot-pounds, with free recoil of 200 lbs into the shoulder.

 

I weigh about 175 pounds, are you saying I shouldn't shoot the 577 T-REX

 

Considering the .577 T-rex throws the same weight bullet just 400 feet per second slower than a .50 BMG, the rifle weighs just 13.6 lbs (not 30) and doesn't have a muzzle brake... you tell me!

 

Maybe i'll wear a recoil shoulder pad

 

Maybe I'll just watch

 

That was funny as sh@t

Why don't I just put the 577 T-REX buttstock against my nut sack & shoot the rifle
