Conical boolits for ROA and other 45 BP revolvers

[Onty]

Here’s my 195 grn bullet design:

Things I’ll be modifying is to lengthen the base that easily inserts into the chamber. Not that I have to be really careful but I’ve wasted a few with them tilting while loading. Now I want more base.

Good design! I just wanted something bit heavier. As for loading, I am not counting on revolver lever. Since we are talking about larger boolit, I think that the only way to press this bigger boolit properly into cylinder is to use some sort of press with stand, on which cylinder could be placed:

I have no experience, but it seems to me one of the reason with conicals not shooting well in the old army is not getting them started straight. The same problem muzzleloaders can have. The advantage a muzzleloader has is a chamfered muzzle crown, which the old army has a sharp edged cylinder. My own thinking is that you need something that will self center, which is why a ball shoots so good. The O ring idea could work, but it seems to me that you could do the same thing with the soft lead and save the money. Keep the hollow base, and keep the rebated section, but replace that lube groove with a rounded or tapered drive band. Something as large as .457" should start as easy as a ball since the bearing surface is so small. That should center the back half, but the front half is still loose. I kind of like your tapered nose idea, but I think it would work better if the taper was backwards.

This is how setup will look when boolit is placed on ROA cylinder prior to pressing into chamber:

Yeah, I created it figuring my 2013 NMA was going to have the slower 1:30” twist. Nope. 1:16” like my ROA. I created that design to basically maximize the projectile while keeping it about the right length for the slow twist.

I’m not so sure they’d need a press. For myself it needs to be functional as is. I wouldn’t want to carry all of that with me to be able to shoot, though of course an additional cylinder could always be carried.

I had also created a 245 grn modified version, but didn’t order a mold for it. Seeing what I’ve seen with both pistols a universal bullet could be made to fill the excess in the chambers, though I’ve considered deepening the Ruger’s chambers, which would give me a longer bullet. A single mold for both guns sounds good to me. And I’ve roughly estimated a 210-230 grn bullet.

Sorry, not familiar with above. Is that some sort of muzzle loading single shot pistol, or rifle? Bought or built?

[Walks]

That loading device is pretty cool. Much heavier then the one I bought 20 odd yrs ago. Clamped to the top of my guncart, I might start Cowboy Shooting again. With a pair of Remington C&B clones.

If there is no enough interest for one of those ROA proposed designs, I will ask Miha to clip the top of Webley 455 mold for about .150":



The only issue is I will have to think about simple tool to make base rebated dia for centering in cylinder. Hope simple bushing with stepped hole should do the trick.

What about this one?

Are you talking about this:

Just 170 grains, very small meplat, no HB. OK for plinking and smaller game. I am looking something that could be used for wild boar if necessary.

Sorry. I was vague. NMA stands for New Model Army, which is the Remington 1858 that is actually an 1863.

I got the Pietta 2013 Sheriff’s model on the bottom.

Blessed and happy Easter!

Her is my (rough, unfinished) idea for a loading press:

Maybe make it so the mechanism can function on a slide to adjust for some different cylinder heights if needed?
It could also be used them to optimize compression equally among cylinders as the mechanism will bottom out once you set the height and load appropriate

With 3 set of holes, 1/2" apart, combined with thread inside plunger, I guess cylinders for all BP revolvers could be covered:

You could just put a adjustable stop on the plunger

No this one, it is 210 gr RNFP

That's IMO better. However, as I mentioned, would like to have opportunity to have hollow base (HB).

The Lee 456-220-1R mould is a heeled boolit for the precussion revolvers. Just cast some yesterday out of pure lead [mine weigh about 215 gr] the heel is .450 dia by about 3/16 in lg to start straight in the cylinder and the driving bands forward are .456. They have a little over a 1/8 in flat on top. This was a new mould and after smoking it the bullets literally just fell out, had to drop them on a double up towel to keep from damaging them, really soft, should have no problem shaving the sides as they are seated to seal the chamber. Can fill lube grooves or use a lubed felt wad underneath.

Looks good. This design is simpler, better than mine, I like it. Did you put any kind of steel or bronze bushing in aluminum block? What is the clamp size/capacity used?

My suggestion; make more and offer to others, I am confident shooter will like it.

I didn't build it. Some guy on another forum did. He manufactured a bunch and sold them there. Failed to deliver on some and disappeared.
There's a bronze bushing in the aluminum block. Also a ball bearing detent to hold it in the up position. It also converts to a wad cutter.
I bought it second hand on the bay.
