Never heard of round balls from a 45 govt. What does one shoot with such a load? How do you hold the balls at the case mouth? Have you had luck with the reduced charge? I tried Red Dot and Green Dot before but my results were very inconsistent.
Unique is my preferred powder for cast Boollits in the 35 Rem. Gets a 204 rngc up to about 1350 FPS.
I do love me a lever gun. 4 centerfire and 3 rimfire.
The trick is to use oversized balls.
A 360 in 38 or 430 in 44 or 460 in 45/70
The neck tension takes care of the rest.
If you load a single round ball there is barely any neck tension and not enough to give a proper burn.
I’ve loaded a single round ball in a 45/70 with decent results but I find that your best bet is to go way oversized like a .490” that’s been sized down to .458” giving it a lot more bearing surface. Then you can seat it just deep enough so it’s maybe .010” deeper than half the balls diamter. Roll crimp moderately
Or the second option where it applies in straight walled cases is to use a small powder charge of fast burning pistol powder and push the unsized .457” round ball deep into the case.
This is popular with the castboolit guys and I’ve read reports that the same powder charge with a round ball seated to its equator will bounce off of a 2x4 where the same charge with the ball deep seated will almost pass through the 2x4
Round balls and light bullets were common for indoor gallery shooting of rifles. Hard to shoot a 45/70 in doors without shooting through the building.
Today guys use them for the same or for quiet light practice target loads. They’re also rumored to be great on small game.
The triple ball load was I believe called the sentry load. This was a military load given to indoor guards. They didn’t want to have the 500 or 405 grain bullets for indoor use. You might kill the intruders and someone in the next room.
The triple ball was very effective but didn’t have the overpenetration through walls that a 405 or 500 would.
The double round balls in a 38 special was actually loaded by Remington as a self defense load too.
The load I shot last night held about a 3” group at 25 yards. That would be bad news for small game. 900 FPS shows about 240 ft/lb energy per ball. Bad new for sure.
