I use Trail Boss loading .38 Special and 45-70. I think it really shines under a 405 gr slug in the 45-70 and I may decide to take an elk with it one day. Burning 13 grains of Trail Boss and buying the cast bullets online, my 45-70 reloads cost me 40 cents each.

I've loaded and shot Blue Dot in some rifle ammo before. Guess I don't see the reason to sneer at whether a guy likes Trail Boss for some applications over other choices. Truthfully I wouldn't be afraid to shoot an elk with that 405 grain slug over TB and it's easy on the shoulder and ears.
