The only one I've ever owned is in 8mm RemMag, and I've found it to kick like a mule (if I don't have the muzzle brake on it). I don't have extensive experience with magnums though, having shot .308 Norma, .358 Norma, .303 Epps Belted (.311 Norma) and a .458 WinMag. Next to the 8mm, the .308 Norma kicked the hardest, but it was on a 6 1/2 pound gun.
