The Barnes 150 tsx .3030 bullet has one heck of a big hollow point. Will open up at .30-30 speed for sure and penetrate like a mono.
I understand hammer makes lever bullets, as does maker. Federal I beleive has a trophy copper loading that might be worth a look.
No doubt a ton of elk and moose have been stacked up with super x power points and corlokts.
I will say, my dad had a bad experience with his .30-30 when I was a kid. I forget what ammo he had but not a handloader or a gun enthusiast at all, some generic soft point. But he hit the bull twice. And it did die, BUT it covered a lot of ground and it simply got too dark and the bush too thick for him and his brother to see anymore. Went out the next morning and of course the coyotes, ravens, and magpies had already halfway eaten it
But they still inspected the carcass to see what happened and both shots were solid front chest hits, one of them hit the scapula funny and it veered hard never actually entering the thoracic cavity or striking any vitals and travelled under the skin along the ribs a long ways down the animal, lodged somewhere in the rear quarter. The other shot shoulder punched it and appeared to have fully smashed and penetrated the shoulder joint and entered the chest, but never exited and it seems only damaged one of the lungs, not both, and probably some other "plumbing" near the heart. And as many of you have relayed in your accounts, an elk can go stupid far with one fully functional lung.
He kicked himself about that for a long time. And wondered if he had borrowed my .270 or his brothers .308 or our neighbors .30-06 if things might have been different. AND MAYBE THEY WOULDNT HAVE! I've heard of that scapula deflection thing happening with .300 magnums too, it does just happen sometimes it seems. But it does seem that the shoulder hit with a heavier or tougher bullet launched with more horsepower quite possibly would have done a lot more damage inside the chest cavity and maybe gave an exit wound for faster bleeding out if nothing else.
Even though it's a slower moving cartridge with a good sized projectile, based on that very limited experience it seems prudent to advise treating it in some ways similar to the .243 and other marginal elk cartridges…get close, use a tougher bullet, and be picky with shot placement, broadside double lung meat saver shots NOT ON THE SHOULDER will surely dispatch any elk or moose that walks this earth without much fuss. But it's definitely less forgiving, versatile, and capable than something like the usual all around guns like .270, 7-08, 7 rem mag, .308, .30-06, and .300 win mag (and in this neck of the woods while it's nowhere as popular as it once was the old .303 British still stacks up a lot of big game as well)
