I really like the Rowland. I haven't bought a conversion for my 1911 yet, but I did convert my S&W 625 revolver. It makes for a very versatile package in one firearm. If you reload, you can experiment with some deer loads that won't beat you up too much...or more importantly, won't beat your gun up too much. Hot loads will accelerate wear on your gun...as will any magnum load...in any gun. I'd go for it and pick up a Clark conversion kit.

I've been using this loading - 16.5 gr. AA#7 Hornady 185 XTP Vel -1421fps

It's got a lot of punch and is still a joy to shoot.

In May of 2000 I worked up 460 Rowland loads in a 20 ounce Patriot.

The recoil of 460 Roland cannot be contained with the light slide of short pistols, given the constraint of reasonable recoil springs.
My 460 Rowland project was to convert a Republic Arms Patriot to 460 Rowland loads with 45 acp brass. The effort resulted in a 42 pound triple recoil spring assembly that most men cannot pull back. The spring force, slide mass, barrel mass, and my hand mass combine to nicely absorb the momentum from 45 acp +P loads, but eject the brass quite some distance with 460 Rowland load levels.

3) 45 Super................185 gr. 12.4 gr. AA#5 1312 fps 28,000 cup
4) 460 Rowland............ 185 gr. 14.5 gr. AA#5 1500 fps 38,800 cup
5) Easy extraction ........185 gr. 15.0 gr. AA#5 *rifle
6) Case starts to stretch..185 gr. 15.2 gr. AA#5 *rifle
7) difficult extraction ...185 gr. 16.0 gr. AA#5 *rifle
8) primer falls out .......185 gr. 16.5 gr. AA#5 *rifle

The Starline 460 Rowland or Starline 45 Super is not any stronger than any brand of 45acp brass, when tested in a full support chamber.
In a poor support chamber, Starline 45 +P has some advantage with thicker walls, but diminished case capacity.
