Model 625 JM & +P rounds?

[Billythepoet]

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

Sometimes, "Because it's fun" is answer enough.

S&W's modern revolver manual shows 45 auto +P is acceptable.

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 ~75% difference in thickness.
.

I would call it a 33% difference going from .030 to .040
or a 25% difference going from .040 to .030

Ooops. Thanks for the correction. No idea why I typed that.

I get your idea but the analogy is a little off.

To go from 38 Special (17K psi) to 357 Magnum (35K psi) power is a ~106% increase in power.

To go from 45ACP (21K psi) to 45ACP(+P) (23K psi) is an increase of just under 10%, which is what the OP was asking.

So this was +P in a JM ?

Ouch! Obviously a double powder charge.

Who did that?

Going from 45 acp to 45 acp +P is not a huge jump . Going from 45 acp to 460 Rowland is . Therefore shooting 460 Rowland in a 625 JM, my analogy is " spot on " . Regards, Paul

I just saw a video on 45 SMC ammo . Supposedly like " +++P " or there abouts . Can someone tell me more ? Not that I have any desire to try shooting in my 1911 , just curious . It's factory stuff , from what I saw . Regards, Paul

Did anyone notice it appears that 3 rounds went off. But looking at the case web for burned powder residue, it appears that maybe only the round under the hammer went off? The case web on the 3rd round isn't visible.

BTW, look how thin those chamber walls are on the inside!

Idk I find that hard to believe. Seems to me that is a double powder charge with a fast burning powder.

Bluedot and I have talked about this quite a bit in my quest to more velocity. I've shot the following load in a 3",4", and 5" S&W 625. Mostly a 5" which is what I carry in the woods and deer hunt with. I'm definitely in the upper level of 45 Super and lower level of 460 Rowland. I don't shoot this load a lot but I have put about 200 rounds through my 5". I used 11.3 grains of power pistol. I've been over 11.5 grains but the best on paper has been 11.5 down to 11.2. The spread stays tight and accuracy is excellent out to 60 yards or so. Don't get me wrong.... this load is definitely a power house. It is very hard to tell this load from most factory 44 magnum loads, which was my goal.

I've recently started playing with heavier projectiles. I've been up to 250 xtp bullets with 8 grains of power pistol. Haven't shot to much and don't have the data in front of me to share.

I agree it would have been but you didn't specify that.

And I agree, shooting 460 Rowland in a 625 is a bridge too far for me also.
