Hi folks, Just thought you'd want to know: I got an email back from Tim Sundles from Buffalo Bore regarding velocities for the .454 Casull from a 16" lever-action Carbine barrel. I asked him about the 250gr. Barnes Bullet that they load: Approximately 2,050 FPS! Hell yes! I think this will definitely be the round I choose for when I go hunting Pig. I imagine it would generate close to 1,900 FPE, if not close to 2,000 FPE; but that might be pushing it just a bit. Definitely close to .45-70 Ballistics in a small, very light, and very handy carbine! The Carbine I'm referring to is a Trapper-style from LSI, the Puma line, under the M92. Mine was a gift from a good friend. It has fiber-optic sights, a nice recoil pad, and a stainless-steel round barrel. Unfortunately, mine is currently out of commission until I find a reputable gunsmith to put the front sight back on; it came off during a range session while firing 260gr. MagTech loads. Unfortunately, the research I've done on the quality of this carbine has been mixed. Back when they were being produced, quality control was either a hit or a miss. Mine however, with the exception of the above problem, has been awesome. I've never fired anything heavier in it than 300gr. loads, so I'm not sure if the heavier Casull-loads in 335+grains in weight would chamber well in this carbine (certainly, anything in .45 Colt, with this heavy-weight bullet, would chamber just fine). If they do, they'd be well-needed for anything you can take in North America; probably upwards of Bison as well! This carbine is no longer sold through LSI in this caliber. However, you can find them on the used market. LSI currently lists the .44 Magnum in the Puma M92 series as the most powerful handgun round available in that carbine/rifle. Hope this was helpful to anyone considering one of these great and very handy little shooters. It certainly gives a nice boom and fireball!
