My new dream CCW revolver that does not exist yet.

Instead of wanting to use semiauto ammo in revolvers, maybe we need a wish list for actual revolver ammo, never mind the moonclip thing.

I'd dream about a carry revolver in 7.62X25mm. It's not DOA. I think the moon-clip thing is a good thing, but perhaps the ammo company would make as a 7.62X25mm Auto Rim.
 
Now that Federal has a .312" HST bullet, my hope is that they load it in .327. The .30 SC parameter of 100g at 1250 fps is basically mild .327.

The only .327 personal defense load Federal shows is an ancient 85g Hydra-Shok.
 
My dream CCW revolver would be a .327 Federal Mag with 8 shots and probably would be the same size as a S&W J-frame, though a tad smaller would be nice.

Alternately, a .25 caliber revolver with 8 to 10 shots and perhaps smaller than the J-frame.

What? Your perception of geometry is leading you astray. 6-rds of 327 Federal just fits in a J-frame with ~.037 inch between rims. Both Ruger and S&W have sold 6-shot 327 Mag revolvers built on their 5-shot 38/357 frames. Ruger still offers an SP101 in 327. It would take a L-frame (686 or GP100) to get eight shots and that would only leave ~.013 between rims. And for some reason other than simple rim clearance when Ruger did make a GP100 in 327 Federal they chose to only make it a 7-shooter. Probably so they could just use the same setup as their 7-shot 357 Mag, but there may also have been concerns about the thinness of the wall between chambers (.043 inch) and the high pressure of 327 Federal.

Ok, being I am not an engineer, your advice is appreciated. So lets say how many .25 caliber of highest power can we get in a J-frame size revolver?
 
I think you might get 7-shots of 25 ACP in a J-frame/SP101. You can get 8-rds of 22LR in either of these platforms.

Never hear of these issues before. Could you please elaborate?

The pressure of firing moves the case moves back against the recoil shield, the cylinder moves forward due to pressure/friction. The pressure in the cartridge causes the shoulder to grow forward filling the shoulder of the chamber, stretching the brass. When everything relaxes the case is now slightly longer and adds friction by pushing the case head into the the recoil shield. If this is bad enough is makes moving the cylinder progressively hard as you shoot more rounds in the cylinder.

I'll take it. Or at this point would an extra round in .22 be a better deal. .22 is not such a stopper, though I just read an article that said these smaller bullets tend to bounce around inside the body and do more damage than one might expect, so...

Right. Doesn't that happen in all brass but more so in bottleneck? Didn't think of that. Thanks.

This particular problem can't happen with straight walled cases normally used in revolvers. There is no shoulder for the brass to stretch against and later push back on the recoil shield. This is not always true with bottle neck cartridges but it is certainly a possibility especially as pressures get higher and tolorances on how much the cylinder can move loosen. This problem can be really bad with lots of end shake in the cylinder.

.22's "bouncing around" is my experience - the small irregular wound tract just takes a little longer to work than a larger caliber.
 
30 super carry… I had a 327 fed mag… and both are now a hard pass. Recoil is as much about perception as it is reality, and noise and fireball add a whole bunch to the perception. The truth of it is that there’s a pressure level that is sensible in a handgun and those cartridges exceed it. Possibly not in long barreled target type guns, but definitely in pocket rockets.

another thing to consider for OP, since the 30sc will likely never be made in a revolver I would suggest one of the 32 mag or 32 long guns but with a new cylinder of proper heat treat and materials.
