Okay I freely admit, I'm dumb. I bought a powder horn and used it today for the first time. Filled it with powder, went to the range, and fille the powder measure. Guess what I see, mixed in with my powder are lots of horn shavings and some wood shavings. I said to myself "Self, that was awful dumb not to make sure the horn was cleaned out before using it". What do you guys suggest I do? I thought I'd fill it with corn meal (maybe) shake the horn a lot and dump it out to see if that works out the loose shavings. Any helpful hints appreciated.
