Finding anything for 45 is getting tough. seems like everything is 50. I have a 45 as well and shoot the Pyrodex pellets and Powerbelts. I have a jug of the Blackhorn 209 on order to try. But the Powerbelts are about the only route unless you want to go with the Barnes expander which is a 40 caliber in a 45 Sabot but they highly suggest you get the Barnes Allignment tool to use this one. Hornady also has a "Great Plains 45 Sabot. Midway USA has all of these. Hope this helps, Good Luck.
