I went to a new (for me) range today and there were 14 of us shooting. A couple were fairly young and had very little muzzle loading experience. Many of the guys were using the pre-measured powder charges in little containers. It appears one guys has dropped his powder load in when his buddy said his cleaning rod was stuck and he needed some help. His buddy helped him and them went back and got ready to shoot. I was walking up to take my shot for a turkey when a rifle went Ka-Boom! It was the helper and of course it scared the hell out of him. We did a cease fire and looked at things and in checking his powder containers found an extra one was used! Fortunately he uses 50 grains in a T/C 50 caliber which can easily take a 100 or more rain load. Lucky boy!
