I tried some cast boolit loads in my H&R 45/70 handi rifle for the first time today. I was using BLC2 powder which was purchased a few months ago and has been used in several other cartridges without a problem. It is also stored in a dark room which is kept at around 73 degrees F. I shot about three rounds through it and the pressure and velocity was fine, all of the powder burned. Then the next round barely sent the boolit out of the barrel. I checked the bore and made sure it was safe toshoot, then the next boolit got lodged in the bore. The powder was underneath of the stuck boolit and about half of the powder looks like new, while the other half is a yellow color.
What the heck happened? I purchased the brass new and this was my first time using it. I may try tumbling the brass in case there is any oil residue on them. Also, I used a dacron filler so I don't think it is due to the boolit lube contaminating the powder.
