Anyone here ever chrono'd their loads through a 625-10 .45ACP revolver? I'm thinking about getting one of these guns but wonder how much the performance drops off when compared to longer barrels. Thought maybe someone here has been down this road already.

Thanks,

Winchester Value Pack 230 gr factory loads chronoed an average of 843 fps for five shots fired with a range of 838 to 857 fps. Temp was 58F and the temp of the ammo and weapon were between 69F and 58F.

FWIW, my 625-10 stung my hand so bad with factory 230s that I sold it. I tried it with the Ahrends combats, Pachy Decellerator, and a pair of S&W fingergroove combats. "Ouch" on all accounts, with the Decellerator grip being the most tolerable. I am NOT sensitive to recoil and my favorite handgun is the 1911. However, my Colt Defender and Springfield MicroCompact both have way less of a "sharp" felt recoil than the 625-10. That thing STUNG to shoot.

Further, there have been some 625-10s that cracked the frame at the bottom of the barrel threads above the yoke/crane recess. S&W is NOT replacing the frames; they are offering credit towards some other new S&W firearm.

I am SOOOOO glad I sold mine, although given the very low production and cracked frames taking more off the market, I have no doubt that in future, S&W collectors will bid up the market price of the 625-10 to "Bloodwork" gun price altitudes.

Thank you, Noah. Had you chronoed that ammo through a 4 or 6 inch gun by way of comparison? This is just pure curiosity.

Thanks for the heads up on the recoil factor. Here is something in return. I was overseas for a number of years and when I got back I met our Sr. Armorer for a firearms update. He gave me the lowdown on the new scandium craze and told me to stay away from these lightweight guns. I was surprised at his sincerity, which really sounded more like a warning. He said these guns have a recoil effect similar to what is felt when hitting a steel I beam with a metal baseball bat. It is sharp and painful.

I searched 625-10 posts and had found your earlier remarks. I'm not a bit surprised at your response to the recoil.

Now that I have been brought back to my senses I'll pass on this project. Thanks for the reality check.
 
Lifer:

In my 6.5" Model 25-2, the same W-W Factory 230s were about 25 to 31 FPS faster the two times I clocked them, one at 47F and the other at 78F.

"Metal bat on a steel beam" is a PERFECT description of the recoil sensation. I call it "OUCH" for short.

IMO, you are wise to step away and fuggedabowdit.

The real benefit here seems to be the knowledged gained by clocking these .45 ACP loads. I know that guns and barrels differ but it appears that even the short barrel of the -10 gave the bulk of the velocity available, while the much longer tube netted little gain.

I've got 4 and 6.5 inch .45 ACP revolvers and find this data to be of interest. Maybe I'll just stick to my 625 MG's.

Thanks, Noah.
 
My 625-10 PD load is a 200lswc over 9.7 AA7, Fed primer, OAL 1.225 for 900fps even. The same load gives me 939fps in my 3" 625-6 and 1005fps in my 5" 625-2. It isn't a max load. I chose it because it does the job, and is OK to shoot. AA7 with the 200gr bullet gives significantly less perceived recoil than factory ammo. I enjoy shooting the thing, and put 50-100rds a week through it, when it isn't at the factory (where it is right now). The gun has a continuing lockup problem which I'm sure they'll get fixed sooner or later. The cylinder backs up under recoil like 29's prior to the endurance package. Not surprising, as the gun has a J-frame size cylinder stop and notches.
 
I don't have a 625-10 but i have a 625 and 625-8. The old one is 5" and the -8 is 4" model.

I load 3.9grs of clays w/230gr bullet for uspsa.
I shot 10 out of each gun a few days ago, only to find that the velocity was:
5" Gun: 759fps SD 9.3
4" Gun: 763fps SD 7.6

Irrelevant, but interesting.

I'm sure that you'll lost some velocity with that short barrel, but 45 doesn't use a whole lot of powder. If it were something like 357 that has a lot more powder and pressure, the barrel length would make a more drastic difference.

I, too, would be interested in seeing a chrono result comparison from one of these little guys.

[edit] Sorry, i'm a little slow on the draw..lol I see others have posted results.
 
I haven't chronied my loads.

In my 625-8 5" I've found 5.2g W231 behind 230 FMJ or LRN to be a real pussycat and very accurate in the 800-1000 rounds I've tested using a variety of recipes.

No recoil issues, no cylinder problems.

I *did* have the most serious leading problem I've EVER encountered, but seem to have resolved that by sticking mainly to FMJ ball ammo.

It's one of my favorite revolvers.
 
I have shot these out of a M625-4 and a M625-6, both 5".

I normally use 13.0 gr of 2400 with these 270 gr bullets at about 950 fps.

I use Pachmayr Compac grips, even though I prefer Grippers.

Paul,
Did you cast those your self? If so, whose mould? If not, whose bullet? How do you guns stand up to your load?

Also, what is the difference between Compacs and Grippers? Do Grippers have finger grooves?

Thanks,

S/W - Lifer
 
I don't believe I cast the ones in the picture. They came from Chunkum's, RIP, moulds.

These came from my new 6 cavity Lee (group buy at Cast Boolits).

The original moulds cast bullets like these.

The Lee is just a little different, with a square lube groove.


Grippers have finger grooves, like the ones on this M28-2.

I haven't torn up a N frame yet.

Thank's, Paul. Yep, N-frames are tough alright. I've seen some 29's beat up but they were all abused with overloads.
 
Here's a couple of heads up comparisons from a 4 inch 625 and 5 inch 1911. Bullets are 230 grain cast RN in mixed cases with Federal standard primers.

4.2 Bullseye, 625= 740 fps, 911= 766 fps

4.0 Clays, 625= 777 fps, 191= 827 fps
