I have the RCBS setup & trim down/reform 308-30/06 brass for use in the 45acp. A 410 wad goes over the powder and then trimmed flush with the case mouth. 62g of #9 shot, capped with a single 53g 00 Buck & crimped. (115g total). The charge is 6.2 to 6.3g of WW-231. It throws a rabbit size pattern with the buck nicely centered at about 20 ft or so.
Headspace & powder charge are critical, but once ironed out, they work good and cycle & feed from the Colt fine. Glocks have a harder time with them.
(How bout wax or fingernail polish to seal the 45Colt gaschecked shotloads?)
