.45-70 is probably one of the easiest to load for. Really fun. I use a stout load of Varget with the hard cast and IMR3031 for the Jacketed SP
 
.416 Taylor. I get fantastic groups with the 400gr Hornady round nose but I can't recall my powder charge off the top of my head right now...
 
50 BMG. 660 fmj up through 800gr bronze bullets. Usually do 215-230gr of IMR 5010 or H50BMG. Recoil in a 35 pound rifle is not bad at all but muzzle blast is significant. Don’t shoot under cover. Get about 30 rounds per pound of powder.
 
375 RUM... Wastes alot of powder like my 300 RUM. A pound of powder dosent last long at a 100 plus grains per load. I also load 450BM, 44 mag, and 45 colt.
