I just acquired this revolver for 2 1/2 " .410 or 45 COLT ammo. It has a 2" barrel and I plan to use it as my primary cary weapon. After carrying 45's, 9mm's, 38's and 40 cal's, I must admit that this little wheeler is quite a gem. It is definitely the lightest of my carry guns and it conceals about as well as a derringer. I am very impressed with its accuracy and its easy feel upon recoil. OK, enough braggin'....what I'm really looking for is a good reload for this gun. I already have the Lee 90358 bullet mold (452-255RF), and it makes for a very nice bullet; and, I've tried a couple of loads using 5 gr. (just above starting load) of Red Dot and 7 gr. (just above starting load) of Unique. They each shot "ok", but I haven't been able to find any load data specifically for a 2" barrel. I have found "some" load data using the following on-hand powders: Bullseye, H-110, Herco, Red Dot, Green Dot, Titegroup, Unique, W296 and Trail Boss. Does anyone reload for this handgun? If so, is any one of these powders a better powder for the 45 Colt?
