i opened my can of 777 tonite to start shooting in preperation for the upcoming season. went to pour the powder into my flask and some came out loose but had big (golf ball) clumps. they just bust up when i touched them so i shoke the powder up and that removed the clumps. i used the powder but the crud inside the barrel got real bad within three shots. that is with swabing between shots. what do you guys think caused this? anybody else had this happen? powder was stored in a controled enviroment in the off season.
