.45 ACP to .460 Roland pressures?

Anyone load 45 ACP to .460 Roland pressures ? I have read a few folks ( one very knowledgable) that it can easily be done. Wondering if anyone here has tried it.

I would not encourage it, and from a pure liability standpoint suggest you work up very carefully following professional load data and all safe reloading practices.
Remington LP brass can not handle it, sp is stronger.
Starline 45acp +p brass and Starline 460R brass are identical in web and head - only difference is length.

Springs must match the load or you will damage something.

Always follow manufacturers ammunition specifications.

Little force is needed to control a man who has been hoodwinked; no force can control a free man, not the rack, bombs, not anything, you can't conquer a free man, at most you can kill him.

And just fyi
A 180 grain lswc from a 7 inch amt longslide with a roland barrel will go through both shoulders and everything in between on a 8 point nontypical buck at 59 yards.

yeah, I wouldn't do it. There's more to it than just brass case strength - you're going from 23k psi to 40k.

In a 'standard' 460 Rowland 1911 conversion (Clark's) you have a compensated barrel and a 22 or 24lb recoil spring with a full length guide rod.

I have no intention of trying it without more information. I like the thought of .44 mag performance from a 1911. Other than a compensated or ported barrel and heavier spring (recoil and firing pin) I don't see why a steel weapon could not handle the pressures ( l'm told by folks who have tried it that the brass handleing the pressure is no problem.)
