460 Rowland the 10mm Killer!?!

[RonDeer10mm]

The more I learn about 460 rowland, the more i feel underpowered with my 10mm and think about converting. I just have one question can reloaders consistently get 1400fps with the 230gr from a 1911, like Underwood's load?

I'm not sure but that's awesome if possible.

I always thought that .460 Rowland was a great excuse to get a S&W 4506. Big, heavy, accurate, and I wouldn't feel bad beating it to death with those loads.

I was ready to jump to the Rowland .460 about a year ago, even got brass but just sort of lost interest when I couldn't get a conversion kit for my Glock 21. Still think it is a good round.

As long as ur fine with running a compensator than ya its BA.

Same deal with the .45 Super, I load mine with 250gr JHP's to over 1,300 fps, even 300gr to over 1150 fps. At those levels (460R level) a comp is required but unlike the Rowland, you don't have to have a special chamber, just a .45 ACP with good case support and stiff springs (and a comp if you're going all out).

Even non comped level loads are still potent. However, keep in mind that with 185-230gr .45 JHP bullets, they're not designed for that much speed. I've shot 185's to 1600 fps in the G21 .45 Super but that's too fast! Same with 230's at 1400! Now the heavier .45 Colt designed 240-250gr+ class is good to go though!

I'd never really looked hard at it, but I've done a little research today and can see why there is an appeal. I don't think I'd be interested though. Based on everything I've seen it really does give 44 mag performance from 45 ACP pistols. But at a cost I'm not willing to pay.

You are shooting a round that generates 40,000 psi in guns designed for around 25,000 psi or less. The only way to keep your gun from coming apart is with an added compensator on the barrel. That really limits holsters and makes for a much larger, heavier handgun.

For guys wanting to put up with the side effects in order to get the power in a semi, then I say go for it. For me I'm content with the performance my Glock 10mm offers and if I need more I'd rather have a 44 revolver.

"The only way to keep your gun from coming apart is with an added compensator on the barrel."
You can always go to a gas-operated action (and honestly, we're talking Desert Eagle level power, here, so it's hardly unwarranted). I need to run some numbers to see if my little Skorparev dealie could run this, since it takes PPSH mags which can feed 45ACP, and I understand Rowland has the same OAL. Or I could do a short-cut on that process if anyone happens to know what a 1911's locking surface area is (since it's apparently enough for Rowland, even if the recoil action is not without a break)

That thar is why 1911 platforms suffered when they put 10mm on 'em.

Harken back to yesteryear and read some of the old problems when they put 10mm on 1911 frames...

Not so bad on the 2011 and newer frames, but for the old milspec...cracks happen.
I'd expect the same from .460 on an old-style frame as well.

Sounds like an interesting round but I'd feel a lot more comfortable with a pistol that had actually been designed for that kind of power.
