I have three 50 cal cap locks
Total Barrel lengths
35” long rifle one in 48” twist
17” pistol one in18” twist
10” pistol one in 24” twist

I use a 49 cal ball and 015 patch 70 grain 2F Paradex with the long rifle. It is wicked accurate with a peep. I think this is the optimal combination or close to it

With the 10 inch Kentucky pistol I also use the 49 ball 015 patch. At 20 to 30 grains the groups are kinda OK at 25 yds if I take the charge up to 40 or 50 grains, the groups start to spread

The 17” Bounty, I have not discharged it yet, but with it’s tighter twist rate, I am thinking she might love a conical bullet.

I am more interested in accuracy than knock down power. Any thoughts appreciated. I am a newbie but I love the mix and match quality of muzzleloading

My CVA Mountain Pistol, 50 cal. Shoots the Hornady PA conicals very well with a 45 grain volume charge of 3f Swiss.
Off the bench at 25 yards it's dead on.

I have a couple of boxes of Hornaday Great Plains 50 cal 385 gr brutes, I thought they might work well in the Bounty, and maybe the Kentucky pistol as well. but I picked up the thought somewhere that the 1 in 48 twist of the Kentucky long rifle is too slow to stabilize the conical round. I plan on trying them nevertheless. I will post my results. Experiment and document.

Don't get caught up in the twist rate thing. That's more appropriate for modern stuff. In the North South Skirmish Association, we shoot Civil War era muskets in live fire competition. Twist rates range from 1:72 to 1:48 with 400-500g minie bullet weights and often shoot one ragged hole groups.
