Default Got a question about a .32-20 Uberti

I'm buying a new Uberti .32-20 Cattleman revolver.

I have and reload for a Marlin 1894CL and a Custom .32-20 Handi Rifle. My load for both is 15.4 gr. H110 for about 2200 fps. Hornady doesn't tell me the pressure. I talked to Uberti CS and they told me to stay off +P loads. I think this revolver will happily use my rifle loads, as hot as they may be. Please tell me if I'm wrong. I'm assuming it's made the same as the larger bored revolvers in this series and can take the heat.

IMHO you need to find out the pressures. That seems to me to be a pretty hot load. Now a days Uberti makes some high quality stuff with good steel but it is still faithful to the original Colt design and should be treated as such.

Ditto. I have one and use my 1894 Marlin loads (5 gr Unique) in mine, but don't use them in my Colt Police Positive which is a lighter frame. Just my experience.

Thanks guys for the advice. I found a load in Hornady for the 85 gr. XTP and 8.0 gr. Lil Gun for 1100 fps. That should do fine.

If you compare your hot .32-20 load to .30 US M1 Carbine loads, you will find that it's chamber pressure must be approaching the 40,000 psi mark. Chamber pressures that high may be acceptable in a rifle action, but not in a 140 year old single action army design revolver. Please use more moderate loads in the interest of shooter safety and longevity of your revolver.

Some of the old lee loader charts for 32-20 say something like: Warning these loads for rifle only.
Later Lee Loader charts had the table divided top from bottom, one for rifle, one for revolvers.
Moral is loads for rifles are almost always too hot for revolvers.

Just seeing this today here. I agree with Blake!


You cab for sure improve over the somewhat anemic loadings that are BP era 32-20, but why? Try my long time favorite, a splash of PB and a 115 cast slug. (Trail boss or another of the bulky SR powders would also work.) Its like a pellet gun form a rifle and shoots in same hole at critter harvesting ranges. (25 yards) Its a dandy rabbit/squirrel loading with ZERO bloodshot or damaged meat. its just like the old 45-70 loads where hunters said you could eat right up to the bullet hole!


These are Colt copies and not the strongest in many cases not even as strong as the weak Colt. I have a couple of these myself. Mitchell, Uberti and Colt My 32-20 is a ratty Colt model P.

hot rodding these old guns and loads is like doing the same to a VW bug. If you wanted more power, why start with a VW?
