.45 Super and/or .460 Rowland in a S&W 625 ???

[Naptown_Gaijin]

Hi Y'all!!

I have a S&W 625 Model of 1989, .45 /acP with a 5" bbl. Recently I have read in various forums that one can shoot .45 Super loads in the 625 with no problems; even heard that S&W "unofficially" says there is no harm in doing so. My question is simply this: do any of you big bore shooters have experience shooting .45 Supers in a 625, and if so, what advice can you give? Any problems with those high power 45 Super loads?

Finally, I have also read that some folks have tried .460 Rowland in a S&W 625 with mixed results.. Some say it works OK, others say the recoil is like a .454 Casul.... and, once the chambers are bored out for the .460 Rowland, the gun will never shoot .45 ACP's with much accuracy. Is there any truth to that? Would Mag-Na-Porting be required, or a better alternative, to the Rowland muzzle brake? Am I crazy to even think about doing a 460 Rowland conversion on a revolver?

I know everybody has an opinion, but I prefer to only hear from you if YOU PERSONALLY HAVE EXPERIENCE with either the .45 Super and/or the .460 Rowland in a S&W .45 ACP revolver.

Thanks in advance.

You should call S&W for accurate manufacturer advice.

Clark's Custom Guns rechambers the 625 .45 ACPs to .460 Roland... hint hint.


I have shot .45 Supers out of my 3 inch 625



They are not fun to shoot.... +P .45 ACP is ok to shoot... plain .45 ACP are fun to shoot.

I shoot 45 Super power handloads out of my 4", 31 oz, Sc framed 325TR, either in 45 Super or 45 Auto Rim S-L brass, with no problems.

Shooting 460 Rowland is a bridge too far for me in a S&W 45ACP revolver.

However I did ream a Ss cylinder for it to shoot my 45WSM (click for more info) which gives near 45 Colt powder capacity (18.9% less) & allows the comfortable loading of 270gr L-SWC bullets loaded to 45 Super pressures in it while still being able to shoot 45ACP & 45ARs.

If you need more than 750me out of your M625 buy a certified magnum revolver.

Blue Dot has a good thing going for him! (I may have to ream one of my extra cylinders to use his cartridge.)

In the meantime, I use 45 Supers in my S&W Model 625-6 and custom Model 25-2,

How about going the other way: .45 GAP in the 625. Gap has a slightly higher pressure rating (23K PSI vs 21K PSI), but I would think that would be OK. As GAP slowly dies on the shelves, I foresee some opportunities to pick up some ammo cheaply. Anybody shooting GAP out of their 625?

Adios,

I've shot 45 Gap out of my 625 for knock down steel matches, but have always gone back to 45acp. The 45 Gap ammo is expensive and more disappointing is Starline stopped making 45 GAP. I had some on order for 2+ years and then they discontinued it.
Back when Revolver was 6 shot in USPSA, someone was making Moon Clips for 45 Gap. Not sure, but I think it was Hearthco. The Brian Enos revolver section will show threads on 45 Gap if you go way back in time. lol
