Tornado, here are some links which will help explain the advantages/disadvantages of cast bullets, premium and factory rounds, meplats, and ammo and or bullet choices. Hope this helps.

335 gr. W.F.N. (2025 fps / M.E. 3049 ft. lbs)
300 gr. J.F.P. (2150 fps / M.E. 3078 ft. lbs)
270 gr. J.H.P. (2250 fps / M.E. 3034 ft. lbs.)
45-70 "Magnum loads"
430 gr. L.B.T.- L.F.N. - G.C. (1925 fps / M.E. 3537 ft. lbs.) (Big game up to 2500 lbs. - Penetrator Load)
300gr. Speer Uni Core @ 2350 fps (3678 ft. lbs.) (Big Game up to 500 lbs. - Expander Load)
405 gr. J.F.N. (2000 fps / M.E. 3597 ft. lbs.) (Big game up to 1000 lbs. - Expander Load)
Now check out what the often overlooked .45 Colt can do in modern, and I do mean modern, leverguns and specific revolvers;
325 gr. L.B.T.- L.F.N. (1325 fps / M.E. 1267 ft. lbs.) (Big game up to 1000 lbs.)
300 gr. Speer J.F.N. (1200 fps / M.E. 959 ft. lbs.) Big game up to 800 lbs.)
http://www.buffalobore.com/ammunition/default.htm#4570As you can see, you have a wide array of choices with which you can choose the right load for your type of game as long as you are willing to put up with the recoil, which even in .45 Colt loadings is noticeable, even substantial.
Even the .35 Remington is available in a heavy load form, which I have used to take deer and hogs with. I've even if though by accident taken two hogs with one round with this load.
220 gr. JFN 2200 fps 2364 ft. lbs.
This has roughly twice the recoil of the factory 200 grain ammo, but the 220 JFN also has nearly the same energy and more velocity at 100 yards than the factory 200 grainers do at the muzzle.
Here are some of the bullet choices you will have for the .444 should you wish to start reloading, which I highly recommend, and always save your brass no matter if you do or not. It can always be out to good use.

280g WFN GC Gas Check gives ease of load development and higher velocity potential than PB. Potent bullet in .444 Marlin.
290g LFN Dual Crimp Groove. The long bearing surface of this bullet makes it very accurate. Wide meplat delivers huge wound channels and the long nose gives maximum powder capacity for this weight bullet.
405g WLN DC GGC Dual Crimp Groove Design. Fine for Redhawks and Anacondas, and in .444 Marlin with neck-turned cases
