I prefer a 370 gr .416" bullet at 2300fps, but it's hard to argue with a 300 gr .429" bullet at 2100fps. Get a bit closer to the critter with the 444 , and your talking darn near the same energy.
Got to consider that lever actions have lot's of moving parts, compared to bolt actions.
Also have to find suitable bullets, with a wide meplat for safety in that tubular magazine.
I'd say the cartridge is fine, it's the rifle that may come in question. Or not.
