That Cape is a tough thick skinned critter. At what range do you expect to shoot it? I don't think I would use that light 1.285". A 500 gr at 1.370" cast with 1/20 would be a lot better choice in my opinion for that tough Buff. That 1.370 will work just fine inside 200 yards or less then I would think you would shoot.
When you get that rifle I will send you some .500 grainers of the original Sharps profile to do your own testing. I think you will find them working just fine for a hunting bullet. Just make sure that that bullet is small enough wrapped for a quick follow up shot in a dirty throat. That .44-77 will bump ut a 1/20 bullet a long ways to fill the grooves and it will end up about .065" TO .075" shorter when the charge goes off.
Thanks for all that Kurt, but, I wouldn't use the 44-77 on a Cape Buff, my 44 in Africa would be for heavy antelope, gemsbok, wildebeest etc,, a buff indeed needs 500+ grains, were I to shoot another with a Sharps, it'd be with my 45-70 and the 530 gr paper patch bullet, again from my 18 twist #3 Sporter.
Except, this time the alloy would be tested pliable down to 12 to 1 or so, the first one was an abysmal failure with maybe 14 inches of penetration, that was a 30 yard shot to the chest with 530 grains at 30 to 1. I believe the hide alone wrecked the bullet, not to mention the chest mass of muscle and bone akin to that of a Sherman tank.
After 9 feet of penetration on a bedded Eland Bull, my old 50-90 with 750 gr greasers would have to be considered as well, those hunting bullets were a bit harder than 16 to 1.
