Still in progress, tomorrow I will look at fitting the horn stopper into place. I got tired of spilling that black gold, So i used a 3006 case, cut it down, drilled and epoxied it into the horn for a handy funnel to put the powder where I want it. The horn tip will slide over the case and be the stopper. Found this antelope horn many many years ago out on the plains. Never seen one before and found out they are harder to find because they are made of hair and fall apart after a while. I plan on rubbing in some boiled linseed oil. Most likely going to use it for rendezvous as it is a big large and bulky, but still pretty hard cool. I've never seen someone use a speed goat horn before!
End cap is oak. That crap is worse than shaping steel!
