9mm; I stumbled on that one last week, those guys really wasted alot of time, money, and effort with that one. They're still only pushing the velosity envelope at standard .45 acp, while the .45 acp is providing us with 1100 + fps velosities, in defensive hp ammunition costing less than $14. per 50 rds. The .460 Rowland conversion is a much better concept, costing less than $300. to convert an existing 1911, and the ammunition is much more affordable. Large diameter bullets are only as good their ability to penetrate, with enough energy to expand on impact while continuing into the target.
Novel ideas in cartridge chamberings for the 1911 will come and go, some will even remain, but the .45 acp will always be the yardstick by which all others will be judged.

DA -
Could you talk a little more about the .460 Rowland and the conversion? How does that match up with the 45ACP?

DA - Could you talk a little more about the .460 Rowland and the conversion? How does that match up with the 45ACP?
The energy of the .460 Rowland is compared to that of the 44 magnum, with velosities of 1,347 fps for the 230 gr. Gold Dot JHP, and a power factor of 309. Compare that to the .50 caliber GunCraft pistol, or the .45acp.
Georgia Arms manufactures the loaded .460 Rowland, as well as Triton. The Georgia Arms loaded for the 185 gr. Nosler JHP will get 1550 fps, with 987 Ft. Lbs. of energy at $25.50 per 50 rds. Their 185 gr, JHP defense load will get 1400 fps, with 805 Ft. Lbs. of energy, at $21.50 per 50 rds. And finally; The Georgia Arms loaded 230 gr. Gold Dot HP will give you 1350 fps, with 931 Ft. Lbs. of energy at a cost of $28.00 per 50 rds.
The conversion Barrel is a drop in, with a compensated bushing, full length guide rod, and 30 lb. recoil spring.
More on the conversion can found at Clark Custom Guns and Georgia Arms. I actually met Johnny Rowland at the '99 shot show, with the Clarks, and Jerry Meculek; Johnny had his .460 Rowland conversion with him , on the Kimber that he shot often on his weekly shooting show. I've read several articles of his conversion from Patrick Sweeney, John Taffin, and others. The Clarks have been the manufacturers of this conversion, and Georgia Arms has been the primary manufacturer of the cartridge. The two have had a long working relationship with Johnny Rowland and his shooting show over the years. |

Nice ... thats very interesting DA. You ever think about doing the Rowland conversion on one of yours? When I first saw this set up in Rowland's Kimber ( Kimbers were more affordable then ), my first thought was, "Not in my Colts". I preferred to play everything safe and remain with the original factory chambering. As time past I saw more reviews as the cartridge gained some ground. My only thought about the conversion on my 1911s would be, why?. I have the 44 magnum in my revolvers and I'm still thinking of a good enough reason to acquire the Rowland conversion. I feel as though if I wanted more than I already have with the 1911's .45 acp, the .460 Rowland conversion would be the straightest line between the two points. Then there would also be the 9x23 Winchester to consider in a smaller bore, or the 10mm. One continuous thought comes to mind as to which of my eight 1911 frames would I put to the .460 Rowland ? Patrick Sweeney tested the .460 Rowland using a Wilson CQB. |
