Howdy! I just scored 8lbs of Unique.. my favorite powder. I have the following guns in various models but the calibers are 45-70, 45Colt, 7mm Rem mag., 338 Win mag, 303 British, 7.62x39 roosky, 12ga. Shotgun, 223 Rem. My question is: can I use Unique in all of those calibers and what game can I hunt with each? ( any game from mice to moose ) Please match calibers with loads and boolits to the game hunted. I promise to try them all if I can. Thank you all!
