You figure out a load for the Colts yet?

I know this won't apply to yours but in the Rugers that 270 RCBS SAA lubed with SPG, which from my alloy weighs about 285 with 21 of H110 or WW 296 is pretty damn good. Softball sized rocks at about 150 yards don't have much of a chance. Figure 1100-1200 fps with this. Do need to tweak it a bit because the powder burns a little dirty at this low of pressure. Probably need to either go to Unique for this velocity or increase charge to at least 23 grains which will give somewhere over 1300 fps. This load will penetrate a 20 inch half rotten oak stump against the grain and a 250 jacketed or a hard cast 250 Oregon Trail with the same powder charge won't. Also in this alloy with SPG lube a 429421 square groove .44 loaded to about the same 1200 fps speed will also penetrate like that.

Most bullets are cast way too hard, makes them brittle and they lead like hell. This 1-16 or so is what Elmer used. Seems funny it ain't been improved on much.
