What loads is an S&W 25-2 45acp revolver up to?
- Thread starter Clark
- Start date
I couldn't tell you what the limit is because I still have both of my 25-2s and they are still in one piece.
I have shot tons of +P ammo out of both of them without any problems. I shot them at the Second Chance bowling pin match for 12 years.
The hottest load I fired from them was a 230 FMJ @1050 fps.
I'm not sure I'd want to try the 45 Super out of mine. They are pretty special to me and I'd kick myself if I screwed one up like that.

The weakest part on the S&W revolver is the bolt stop cut which they put directly over the walls of the chambers. All N frame guns use the same sized cylinder (externally), so the bigger the bore, the worse the problem of the bolt cut becomes. A .357 M27 is not much of a worry. Still plenty of steel at the bottom of the cut. A .429 bore on the M29 makes it pretty thin down there. Your M25 is bored .452. How much metal do you think is left at the bottom of the notch? Personally, I would avoid +P loads in this gun.

Clark will convert M25 as well as M625 to .460 Rowland.
Jim,
When I have a 38sw breaktop I paid $35 for and will never shoot again, I tend to overload it to see what it will do.
But this 25-2 is such a nice gun, and I have $420 into it, that I would hate to blow it up for one data point.
I am getting more tempted to ream it out to 45 Colt and seat at 1.4". Then I could keep the pressure down and get the velocity up.
How much are replacemtn cylinders?

I quoted their catalog because I didn't think a reputable shop like Clark would rechamber a gun for a round it wouldn't handle. But I don't know for sure and I don't care because standard .45ACP is about all I want. My curiosity does not extend to wrecking a gun of any price.
Reaming a .45 ACP/AR out to .45 Colt will leave you with about .030" excess headspace which I would expect to give spotty ignition.
A replacement cylinder after you have ruined the original by reaming or overpressure will be at least $120 from Numrich, if they have them for a gun several years out of production, probably more, my catalog is not current.
A M25-5 .45 Colt cylinder will not fit, it is longer, same as a M29 and the barrel breech protrudes too far into the frame to clear. If you could find the rather unusual M25-3 .45 Colt cylinder, it would work; if you cut or replaced the little cylinder stop stud on the left frame.

I have a 25-5, 6 inch. The gun is fitted with an additional cylinder for .45 ACP. I use a load of of 630P and a Speer 230 grain JSP, to give about 1100fps. The Smith loves them.
My normal loads for this gun fitted with the ACP cylinder is the 230 grain HydroShock JHP.

The M25-2 is a wonderful piece, and if mine is typical, as accurate and powerful as any 1911, including customs; with the advantage of capability with an effective SWC bullet and no feeding worries. But that thin cylinder wall has to make you cautious. I've loaded a few 260-grain .45 Colt slugs (the Lyman #454424) with Unique to mid-900 fps velocities in Auto Rim cases, and that's about as far as I'd like to go...mostly I use the 200 gr. SWC #452460, sized to .453", over 4 grains of Bullseye pr 7 grains of Unique, the Lyman book load. This produces gratifiyingly small groups to 50 yards and has plenty of power for a .45 ACP. I'd never use the 25-2 for hotter loads...isn't that what the Ruger .45 Convertible and T/C Contender are for?
