What We Want to Shoot: .460 Rowland
Review Uncategorized - 09.09.2011

The .460 Rowland is one of the most unique chamberings of the modern era.  It was the side project of wildcatter, gun TV celebrity, and shooting enthusiast Johnny Rowland.  His basic idea was to make a 1911 shoot like a .44 Magnum.  He more than succeeded.  With a name that rock-and-roll, what else could anyone expect?


Left: .460 Rowland, right: .45 ACP

So yeah, the basic gist of it is big bullet, high pressure.  What's impressive is how simple the design is; in fact, if not for its simplicity, the .460 Rowland wouldn't have ever made it.  It's based off the .45 ACP; hell it downright is a .45 ACP.  It uses .45 ACP brass, primers, and bullets.  But not the powder.

Pistol powders have changed, gradually, since 1906 when Colt and John Browning finalized the .45 Auto.  So has metallurgy and manufacturing in general.  With the right chamber, you can absolutely crank up the pressure on a .45.  A lot.

SAAMI pressure for .45 ACP and .45 +P is 21,000 and 23,000 PSI, respectively.  .460 Rowland starts at 40,000.

So a couple of things had to happen.  Even though the case looks as though it's destined for .45-hood, it's left 1/16" longer than .45 ACP, and it's a little thicker to cope with the pressure.  Because the bullets headspace at the case mouth, adding a little extra length prevents .460 Rowland cartridges from being chambered in .45 ACP firearms.  This doesn't change the overall length of the cartridge since the bullet is just seated down a bit lower, meaning .460 Rowland uses .45 ACP magazines without modification.

And as is the case with 1911s, beefing up their recoil springs just isn't enough.  At 40,000 PSI, the pistol will cycle too quickly to be reliable; the barrel must be extended and use a compensator.  That's it.  Very, very simple.  To shoot it, you need a special barrel and recoil system; you can use your current handguns.  You don't need any special reloading tools for it, either.  You can use regular .45 ACP dies and equipment.

To achieve this, Johnny Rowland got together with Starline Brass and then later Clark Custom Guns, and presto, one magnificent cartridge (for amazing looking guns).

But the thing that makes the .460 absolutely unique is quite how successful it is.  We're not talking about one firearm manufacturer or one ammunition company working out a niche cartridge to highlight a new product of breathe life into an old one; we're talking about one dude who, with the help of a small handful of gun and ammo experts, managed not only to make an impressive new cartridge, but develop an entire ecosystem of supporters, including major gun names like Wilson and Cor-Bon.  .460 Rowland has legs and it strides.

While the whole thing started out with 1911s, Rowland offers .460 conversion kits for Smith & Wesson M&P pistols, Springfield XDs, and Masterpiece Arms' MAC 10 pistols and carbines, and there is an AR upper is in the works.

We don't expect the .460 Rowland to elevate into the mainstream, but we don't expect it to die off, either.  And the more we talk about it, the more it's what we want to shoot.  We don't even need to go hunting with it or anything.  Give us a .460 Rowland and some bowling pins and we'll do just fine...

Heh - another one that I have. In fact, we did the BBTI "chop tests" of this cartridge in May and will be posting the data soon with our site upgrades. And the performance is pretty impressive - a friend is looking at having a 5" barreled PDW made for it. If he gets everything sorted out, I may wind up with one, as well. Be a heck of a little gun.

One of these days, you and I are going to have words.  And bourbon.  And bullets.  Not necessarily in that order.

Update/Bummer: When I wrote this, I was under the impression that Masterpiece Arms was still manufacturing uppers for their Mac 10 derivatives.  Unfortunately, they aren't.  Send them an email, maybe they'll crank out some new ones.

But there is another carbine kit that some people might find even more impressive: MechTech makes a .460 Rowland carbine upper for 1911s that costs $350 (for the basic model without rails and stuff).  It is definitely something worth shooting.

I might have to buy an xd or another 1911, I would'nt want to do this to my SR 1911.

How about a RIA ? I just bought and older P90 Ruger, that would be a kick ass pistol !

Is there anything in the "beefed up" mods that make it impossible to shoot a regular .45 ACP out of them? Similar to .38/.357, you can shoot a .38 in a .357, but not vice-versa. I know you can't shoot the .460 in a .45, but can you shoot a .45 in a .460?

You can if your extractor is strong enough, it will hold the .45 ACP in place.  But you might see some accuracy issues (just like shooting .38 through some .357 snubbies); and also the recoil spring is much heavier and the gun might not cycle.  Ideally you should swap barrels/springs before shooting .45 Auto.

It's also way cheaper to get a .45 ACP pistol and use a conversion kit, since the Wilson Combat Hunter costs $3700-ish bucks.

... someone should mention this to the DOD. If this were to replace the M9 it sure would bring it to the mainstream and cut the cost of ammunition.
