But you added "upper end" and varied from the original point

What I was saying and, I think what Gary was saying, is there is no advantage to using the 460 Rowland chamber or brass in the Contender.

The longer Rowland case prevents it from entering the 45 ACP chamber. It does not increase powder capacity due to COAL being the same.

As far as "upper end" loads, the Handloader just has to use good sense and recognize what gun he is loading for.

I have the 45 Colt in Peacemaker Clones and 5-Shot Customs. The "upper end" loads vary with the gun.

This is exactly why I leave out one component when posting. I post the gun, powder, bullet, cartridge, OAL, etc. But, never post the charge weight.
