While I don't have a 44 Mag., I do have three Rossi Model 92 Puma's, .38/.357Mag. carbine, 44-40 Win. carbine, and a 45 Colt rifle. All are fine rifles, work well, and are a bunch of fun. I don't know, but just thinking out loud, I suspect a steady diet of full pressure loads in either the .44 Mag. or .454 Casull chamberings would lead to an early demise! Read that as 'loosening things up a bit.
