460 Rowland / wheelguns?

I thought the 460 Rowland was identical in dimension to the .45 ACP...the difference being that the brass is different and built for higher pressure. You use the same bullets for reloading, but different brass.
 
You're thinking of the 45 Super. The Rowland has a longer brass case so it wouldn't fit in a standard .45 Auto chamber. I think it would be like shooting hot .45 Long Colt loads in a 625. Not recommended for shooting a lot, but OK for woods carry. There is someone on here that had his cylinder bored out for it. Clark used to ream 625 cylinders for this conversion. I would stick with the .45 Super and not risk blowing the cylinder. Rowland is 40,000 psi.
I asked this same question when I was thinking of converting my 325PD to Rowland. I sold my 325Pd and bought a Night Guard 325 with the ss cylinder to replace it and am sticking to .45 super.

I do not shoot 460 Rolwand, but have have put many thousands of 45 Supers through my firearms. I might
have gone with the Rowland, but it did not exist at the time. When it came out I had so much 45 Super
brass I chose not to switch.

There is not a problem with either cartridge in a 625. However model 25s are another story.
 
I have a 3" 625-3 Power Custom Combat that was rechambered to 460 Rolland.

The reason for the Rolland was to offer a shell case that when loaded hot could not be put in a gun it did not belong in. Same deal as 38 Special and the 357 Magnum being made longer so it will not chamber in a 38 Special.

The 45 Super will chamber and Fire in anything a 45acp will. This can be a problem with a semi automatic.

You have 3 thicknesses of 45 brass.
45acp
45acp +P (Heavier)
45 Super (Same brass as 45 Win Mag 45acp Length .89)
460 Rolland (45 Win Mag Brass Length .955)

I have not loaded any 460 Rolland in several years. No loading data on my ammo boxes. I did not get close to Max loads.
