Will the Lee conical .450 200gr bullet seal up the chambers on a pietta 58 remington and an Uberti 1860 army?

I would think it would because there's more surface area.

Let us know if you can fit the conical under the rammer in the Colt. It is virtually impossible with a Pietta but only takes a little bit of jiggling to get them into my Hartford ASM 1860 Army. The Remmies: no problem. They seal well and shoot a bit higher than the ball due to the longer barrel time and greater recoil.

Lee conical 450-200:
In my opinion they should fit. I use them in Pietta army 1860, cal 44.

I've seen on You-tube - those being fed to Uberti.
Also, I saw Uberti user manual, and they recomend RB and / or conical.

I was thinking to purchase one of the Uberties, so after you try, pls let us know about accuracy of Uberti with conicals. In Pietta, RB works better. (more accurate)

the majority of modern BP revolvers are pretty consistent in chamber diameter
of around .446 to .449.
So yes the Lee mould .450 and 200 grn will seal it. I use it myself.
However, I would recommend filling the grease grooves with a lube of your choice.
Many people make their own of beeswax and tallow (lard) cooking oil.
I prefer to be tradional in lube and use what they realistically had back then.
Beeswax, tallow.
Paraffin was distilled in the 1830's but how common was it I don't know.
Olive oil was common in Spain and Italy but how common was it over here?
And yes some revolvers the loading area is not large enough to allow the use of conicals.
But if you are not adverse to doing it, a dremel, a small round file and emery cloth, you can open it up enough to allow using them. Then just reblue the area.
I did it to all of mine for versatility in what I have available.

Dear all

so far i am using .457 round balls and 20 grain BP and filler (coffee) .

For using conicals is it mandatory to reduce the BP ?

What is your experience?

The rule I follow was oft quoted years ago: you cannot overload a blackpowder revolver with blackpowder.*

*Steel frames only, BP substitutes like 777 were not invented yet.

If you use more lead (conical or double ball load) you have less room for powder. It is that simple. A conical will take up more room therefore you can't put in as much powder or filler. I use 30grs (vol) of BP in my Remingtons as a maximum load when shooting conicals. No wad or filler. It is a nice "thumper".
