Yes

The daddy to your Webley 38 you have been tinkering with. I've been tinkering with this for a month. Fiocchi loads a 265 grainer that I have two 50 round boxes of that only do 550 fps or so. I loaded some 250 Remington lead over 4.3 grains of Unique and taper crimped over the ogive. These did 650 to 675 fps. Pretty accurate

Then I spent hours making brass from 45 Colt on a Unimat lathe. I set them to 45 ACP length and thinned the rims. Loaded the 250 grain Remigton with about 5.8 grains of Unique. Terrible accuracy and the boolits pulled there taper crimp. The last one pulled out completely and squibbed but exited the barrel. I shot six more checking each for boolits jumping the crimp. All pulled away somewhat and the velocity spread way out and was only in the 500fps range. The throats on these guns are really tight. I should break down and order the 265 grain RCBS hollow base mold for this revolver.

I am using a 45 Colt sizing die and 45 ACP expanding, seating and crimping. I need to roll crimp over the ogive with the Remington bullet. Does the 45 ACP RCBS carbide seating die roll crimp? I've always used a separate taper crimp die.
