RIFLE MAN
Two very differnt animals, though the 454 Casull was bred from the 45 LC.
In "normal" guns, the 300 grain Winchester loading WILL do a legit 1700 fps, whereas the 45 LC in a FA gun will be at the upper end around 1300 to 1350 fps...or so.
Make no mistake of it, the 45 LC in a strong handgun will edge the 44 mag in killing power by a goodly amount.
In the killing field, the 454 Casull has no peers in my observations. I would give it te edge over even the 475 Linebaugh and 500 Linebaugh for just raw slap down power.
Russian boars have been said to be the poor man's Cape Buffalo. They're tough as nails and if not hit hard with something adequate, they more often than not will charge. IMO, ANYTHING that drops em as fast as the 454 is a serious arm indeed.
I, as well as others, have asked for the 454 in a lever gun as this would be just about the berries for puckerbrush shooting, animals that shoot back, and in general, just about all we shoot that is edible :wink: It would seem that a 300 grainer would easily make 2000 fps + out of a 20 inch carbine barrel, and as most already know, the 454 is one very accurate cartridge, even in the handgun.
If I were to want a 45 cal in a lever gun I reckon I would go with Marlin over Winchester as I have never been a fan of the Winchester lever guns. Too, they rattle like castinets, and most do well to group 4 inches at 50 yards. The Marlins just plain shoot better, and as far as I'm concerned, are stronger than their competitor.
I'd load up some 300 Hornady XTP pills over a proper does of 296 that was loaded top end for the Ruger Redhawk. Providin there were no pressure signs in the rifle, I'd sneak up a bit from there. Once I got in the neighborhood of 1500 fps I'd call it a deal and go light something up with the combo.
I would think it would be the cat's meow on good sized rooters, as in my observations, the 45 LC does em nicely out of the handgun.
On the other hand, if you just want to pound the snot outa em with an off the shelf 454 Casull, I would opt for a Raging Bull Taurus as it is affordable, and man do them suckers ever shoot!
Just my 2 cents on the subject
