2 round balls in a single case

Yes, the duplex loads were what got me into reloading.

I think I did 7 grains of Unique to start, but moved up to 7.5 or 8 grains over time cuz I needed more pressure for case obturation. I shot mine in a Ruger Redhawk tho, so I had a lot of room to go over standard pressure and I doubt I did.

Last time I did any duplex loads I used a .454 ball first with a .451 ball on top. The .454 ball seals the bore and prevents gas blowing by, so there was no reason to have the top ball be the same diameter and my goal was to further reduce pressure, but also to cause more disruption so the spread of the balls would increase and it worked, I got about a full inch of separation between the balls at 10 yards.

Only thing I would advise is you lube the balls with Lee liquid alox to prevent/reduce leading.
 
I have often thought about playing with duplex and triplex (multi projectile vs the same term meaning mixing various powders together) but never got around to it.

What’s your load data?
 
I used to flatten oo buckshot in a mold I machined out and shot two at a time in my .357mag.
They would stay within about 6 inches of each other at 15 yards.
Still have some around here somewhere.

Matts Bullets sells stackable 75gr wadcutters for .357mag now for loading two at a time.
About what I was doing.
 
I was able to get 3, .431" balls into .44 magnum loads by grinding a flat on them where they touched.

IIRC they had a spread of @ 6 to 9 inches at 10 yards.

They weren't really useful for anything, but I did use 'em once in a wager with my son about who could get more hits on a silhouette target in 5 seconds, him with his P-220 or me with my M-29.

I won!
 
I'm using Starline brass, CCI 300 primers, 6.4 gr Unique, a .451 RB in the case and capped with a .454
 
I have never been tempted to do this. What would the loads be good for that a accurate shot with a real bullet would not do as well?

Nice bet :D

Yeah, I think you over did it with the 3 balls in a .44 Mag case, I think 3 balls is best used only in super magnum cases like .357 Max, .445 Supermag, .460 S&W Mag or .45-70. Have a lot more powder to work with and you don't have to put flats on the balls, which I think is what caused such a large spread at short distance. Like I said, I've gotten an inch spread at 10 yards with my .45 duplex loads.

It's when you can get a tight spread like that where they become useful. A double tap with each shot is very effective, faster bleed out time. A triple tap? Well... that's even better and one reason I wish someone would make a double action for .357 Maximum. Just need to put a big warning on the gun telling people not to shoot 110 grain loads, that's what causes the flame cutting issues.
 
Bob Milek was getting 4 projectiles in a 357max in a G&A article back in the late 80s or early 90s.
It was fun, interesting, and totally useless project according to his summary.
 
A "project" for people with to much time on their hands or "cabin fever":)
So you think two hits in the the chest with a pair of .45 round balls will bounce off a man or deer because the people who loaded it weren't being serious and were just bored?
 
I've done it in a shotgun before. 2 (or more) 58 caliber round balls will fit in a shotcup. Through a full choked shotgun they held within 10" of each other at 50 yards. I could see some usefullness for this load as a short range stopper for deer or pig sized game if legal. Not legal in MN, but I had some .58 round balls as part of an auction lot to find a creative use for. They also made a good single projectile load with the addition of some wadding to fill the space, which would be useful for inexpensive "slug practice".

Well gee, I just don't know?
Does Buc shot penetrate better than a slug?
142 g4 bullet x 2 or a 284 bullet? Let us know the next time you shot someone or a deer.
Has Taffin or Linbaugh don any studies on this?
Words like, playing around, for fun?
Perhaps you can do a ballistic review on this?
Ballistic gel. wet news paper, water jugs etc. Penetration ,wound channels permanent and temporary I guess expansion is not relevant
Cutting edge of ballistics.

Lighten up Francis, it was said with a :)
 
Some guys fool around with two patched balls down a muzzleloader. I usually hear reports of close grouping (like a few inches) at 50 yards. I have never been tempted to try. If I want more than a patched ball, I figure a 400 grain conical is plenty.
 
I got a Lee 116gr .429 WC mold in a lot of vintage 44cal Lee molds I scored online awhile back. Don't see a real good use for it. But I am considering stacking a couple in 44 mag and 44 special cases just because. Could be fun if not practical. And a little fun sounds pretty good as I'm looking at a 30 day stuck at home scenario. Lol

Be well folks
 
I thought this was kind of interesting. Especially the "For law enforcement use only" statement on the box.

They can't be all that old, the box has a UPC.

OMG, I had no idea a commercial outfit made this ammo, let alone it be Remington. I mean, this must have been back when Remington actually tried to do something innovative and not just stand on name recognition because it was bought by an investment firm.

I did a search, it looks to be old stuff as I'm seeing posts from 2002 referencing that ammo like it was something much older than 10 years ago, which would be the 80s, which was the last decade police revolvers saw widespread use.

Man, I have so many questions when I see something like this. Like, what LEO departments or groups were asking for this? Why did Remington label it for LEO use only? Did they have some legal concern that shooting multiple projectiles from a handgun would turn it into an unregistered short barrel shotgun? Why was this ammunition discontinued? Poor sales, poor performance?

I wonder a lot why ammo companies today don't make anything like this. I can understand two 000 buck pellets in .38 isn't all that exciting, but two balls in a .44 or .45 Colt packs a wallop. Would be great for home defense as it's very unlikely one or both balls would penetrate thru an intruder and if they did the balls would probably bounce off the wall.

You could say that this type of ammo really is balls to the wall.
