those who listen with open minds learn, I got the gun for less than half its value cause it wouldn't shoot, notice bullets are sized .312
 
Interesting Utube about big guns and powder. Guy gets into old powder and deteriaton of same. Expected SD is 5 fps! Degreaded drops to 35 fps. Degredation takes a long time but their powder is stored in proper environment. Interesting, he talks about a poly plastic coating on the powder bags that reduces wear on the barrel.
