I have a Ruger #1 rechambered for the 460 Weatherby magnum, and a Dakota 76 custom rifle chambered for a wildcat cartridge based on the 416 Rigby case necked up to 475. The recoil of the 577 Tyrannosaur at velocities of 2150 fps and below is comparable to the above mentioned rifles. Once the velocity gets to 2400 fps, then the recoil is very severe. And at our maximum of 2581 fps, it is plain painful!
