I had some time today to play with a couple of ideas for bullets to use in my .50-1 3/4". The one on the left is a scaled up version of the .40 caliber bullet I developed for my .40-65. That bullet shoots amazing well for a relatively short .40 caliber bullet, 1.250". I also scaled that design up to .45 caliber for a friend and it is shooting well in his .45-70. So I thought why not a .50 caliber model? Trying to keep the weight near 473 grains in a .50 caliber the length to caliber ratio is kind of short. So the nose had to be adjusted to not be more than half the length of the bullet which resulted in a secant ogive. Not that that is a bad thing. So I kept the OAL to 1 1/16".
The bullet on the right is the best I could come up with based on the info I got from Stephen Borud here. It would probably make the better hunting bullet. The 525 grain bullet I used for hunting with this rifle in the past was much more pointed and cast soft it was very effective on deer and antelope so I believe the round nose would work fine for hunting. Since I'm not really looking at hunting with this bullet I am leaning toward the round nose.
I doubt I'll have time in the next two weeks to cut a mold, though the blocks are ready now. It will be a base pour mold and therefore flat base, which I prefer anyway. I like the round nosed paper patched bullets I see in pictures of the original Sharps cartridges, but getting that configuration into a .50 caliber bullet only 1 1/16" long isn't as easy as I hoped.
I welcome your advise and suggestions. Thanks.

Does anyone have some thought on either version? Or another suggestion I can
try?
