Just finished a kit gun.Pederosoli Kentucky Bounty Hunter,50 cal with a 16/9/16" barrel with a 1-17 twist,12 lands and grooves. There listing only show one load. Using a .490 ball with 25gr of FF. Does anybody have any more loads one can use,and possible loads for 240 gr or 300 gr XTP with sabots?? Really need your help fellas. van. Email me at dickweedv@yahoo.com

I have never heard of a BP barrel with a 17" twist that would stabelize round balls at all! I would think with that rate of twist, if it were mine, I would try heavy conicals such as T-C Maxi-balls and there are a lot of other good bullets on the market. Round ball rifles generally have a twist rate of 1 turn in 60" to 72".

van,
The rifle loads I posted here are totally unsafe in your pistol, and I have deleted them for safety's sake. See my post below for safe and realistic info.

I am sure you are just trying to be helpful but, you are giving RIFLE advice and Van has a PISTOL!

OldGuy,
Oops, you got me there. Thank you. I was so incredulous about the twist rate that I missread the barrel length. I will go back and edit that post.
Van,
I would not try any more than 50gr of FFG or an equivalent volume of Pyrodex with a prb.
If you really want to try something heavier, I can't find a listed mould that would work. You might be able to get away with a very light .44 bullet in a sabot (maybe 200-215gr), but nothing anywhere near as heavy as you are proposing, and at those velocities, you would get no expansion, even with a soft lead boolit in the sabot. A .50 cal rb is about 175gr, and probably more than you'd want to be shooting many of in a handgun. That's enough for a coup-de-gras on a downed deer, and it will sure turn some heads at your local range.

Well fellas i thank you for you input,and here is what has happened. First off i also was thinking about the twist,from what i have read,and somebody must be wrong for as with that twist it surely is accurate. Ican put shooting off a bench with sand bags a 5 shot group at 50yds in a 2" circle. So, it works that way with the factory suggested loads.I did try a 45 cal,240gr.xtp with a sabot using 25gr of FF.Somewhat more of a muzzleblast than the ball,but shot in the same spot. So,just an update fellas. Van
