Re: Roundball pistol loads
Bearing surface is very small, so velocity needs to be kept low. You lose a whole lot of case volume with multiple ball loads, so you can't use even starting charges for "equivalent weight." Be careful. A good place to look for more info would be here:

Re: Roundball pistol loads
I tried to load some .452 roundball for the .45 ACP some years ago...I don't remember the powder brand or weight so in the interest of safety i won't guess. The biggest problem was getting a bit of crimp so the ball wouldn't push into the cases while feeding. I did get some to fire...naturally, they were too weak to cycle the slide. If I were to try again I'm thinking a bulky powder like Trailboss might work....if you could find a load that would not leave any unused space in the case, the balls couldn't set back.
Re: Roundball pistol loads
In my 44 spl. I use a light charge of Bullseye for a single .433dia RB accuracy was exc. for double ball loading I used a charge of Unique slightly under min. for a regular 240 gr cast bullet the round balls weighed 120 grs each. The older Speer manual I have lists RB loads.
Re: Roundball pistol loads
38 spcl cases may hold double for you, depending upon manufacturer. 357 cases are usually tapered thicker internally, so will bulge if you try to multiple. i used to shoot triples of 60 grain wadcutters in 38 cases with about 4 grains unique. usually had 6" spread at 10 yards.
on a related note, buckshot of double 0 size is correct for 30 caliber applications, IIRC.

Yes, I have used them (00) before. Thirty-couple years ago I actually shot two squirrels with the 30-30 and round ball. A small dab of Unique worked there. It took a lot of practice, and more than two misses until I got two on one afternoon. Once done however, it no longer seemed worth the effort.
