Nice work Semi! I killed a nice 9pt buck a few years back with a gun that was loaded for over a year on a clean barrel. I didn't do it on purpose either, I leave mine loaded the whole season until I shoot a deer with it, or shoot the load out at the end of the season. Just forgot that time to shoot it out at the end of the season, and when I grabbed it out of the safe the following year I was surprised it was still loaded. I use a pink ribbon on mine

I had a powderhorn a while back, just didn't like it. Not really sure what the deal was with it...just for some reason it didn't feel right when looking through it. Looks like yours is shooting fine.
