Model 625 JM & +P rounds?

[jski3]

Is the Model 625 JM good to go with 45ACP +P rounds?

Smith's website has:

What's the point of using hot self defense ammo in a target gun? Yes it will handle it but why?

What makes this a target revolver? I am curious as I like the 45 ACP in the N frame.

With a 5" barrel, or less, I don't consider the 625 to be a target revolver, necessarily. You can shoot all the +p out of it you want.

 

[murphydog]

The maximum listed pressure for .45 ACP is 21K psi and +P 23K psi, or less than a 10% increase. You're not getting a huge performance difference between the two.

But since it is a modern, currently produced S & W product, I would just call the factory, or if you have one refer to the owner's manual.

Maybe I am missing the point here. The gun will handle commercial SD loads just fine. I guess I don't understand why hotter loads are needed?
As for it being a target gun, mine was one of the most accurate revolvers I have ever owned regardless of barrel length.

Simple. Better performance . I carry when checking and feeding my cattle and am occasionally get a shot at a coyote or deer if in season. It is one of my favorite calibers. Lately have been carrying a smith 69 however.

Handloader ,agazine number 306 has a plethora of loads +p 45 auto rim by Brian Pierce. Great data

Doesn't Clark do 460 Rowland conversions on these? I've heard of many people running 45 Super through them. I'm not suggesting you do so, but I'd be interested in hearing an expert opinion on it.

Saw this on another gun forum:

S&W has stated that they 625 will fire .45 Super rounds with no problems. I have been doing it for years. I shot 260 gr. heavy loads for pin matches. So did a lot of other guys. Shoot all the +P you can buy.

Does this ring true?

Since the 625 is built on the N frame, which is also used for .44 magnum models, why would it have any issues with .45 acp +p?

 

[jski3]

It's all about the cylinder. Can it withstand those pressure levels?

 

[Billythepoet]

Wall thickness under cylinder notch. Being .452-4 vs .429 in a .44, leaves less material.

Assuming they're starting from the same cylinder blanks, that's a good question.

ALL good condition Smith and Wesson Model 625 revolvers chambered for the 45ACP cartridge are 100% safe with 45ACP +P ammunition

You can shoot all the +P you want

As already mentioned, many of us use our Model 625s for 45 SUPER and even 460 Rowland

These are STRONG revolvers built on a robust frame

I have been a hand loader and shooter of 45 SUPER since just after it came out in the late 1980s.

I do not keep spread sheets on how many rounds go through which guns, but I have put many tens of thousands of 45 SUPERs down range with the two 625s pictured above

 

[BLUEDOT37]

All N-frame cylinders, irregardless of caliber, have a diameter of ~1.710".

At it's thinnest point, the cylinder lock notch, my S&W 45 revolvers average .030" thick (outside chamber wall thickness minus the lock notch's depth). My S&W 44 Magnum's average .040" thickness. That's ~25% less in thickness for the 45.

The 44 Magnum's max SAAMI pressure is 36K psi. 75% of that is 27K psi, well in excess of the 45ACP (+P)'s SAAMI max of 23K psi, which is one way to look at the 45ACP's potential cylinder strength.

I frequently shoot (+P) handloads in my 25/325/625's & periodically shoot 45 Super handloads. I've not seen any ill affects from them.

(- 44 Magnum SAAMI Proof loads run ~50K psi -)
(- 45ACP (+P) SAAMI Proof loads run ~32K psi -)

Groo here
More than one of the heavy load makers has stated they test there 45 super loads in m-25 revolvers.
I would have some 450 or 45 super or 45 ar [heavy] for big stuff
with 45 acp or +P the rest.
Remember, they are called "Horse Pistols" for a reason.

What exactly is that unfluted revolver? I don't see it in S&W's online catalog.

I have a different thought on the subject . When I want more power I get a different gun . I wouldn't think of trying to make a S&W model 10 into a 357 magnum using real hot 38 special loads .
For ranch patrol , a Ruger Old Model Vaquero in 45 Colt is the ticket . They are built on the 44 magnum frame . I have one and it's incredibly accurate . It will take those " Ruger Only Loads " or you can back it down to SAAMI spec's and still have a very potent weapon . This is just my .02 cents worth on the subject . Regards, Paul

Not trying to be confrontational but this doesn't seem much different than what the OP is contemplating since the standard .45 acp and .45 Colt loads have very similar ballistics and the "Ruger Only Loads" are basically .45 Colt +p+ type loads.

I would think that he could probably achieve similar performance with Buffalo Bore's .45 acp +p loads in his 625?
