I load her up with 83 grains FFFg Goex and pack a .50 cal. 240 grain XTP TC Mag Express Sabot on top of that and she does ok. She's taken a few deer in her time. I don't know if you can make out the Made In China stamp on the barrel or not. I don't even remember what the rate of twist is. The ramrod is made from my TC Hawkins ramrod. The one that came with this gun was plastic and broke a long time ago. Sorry about the last photo being blurry. I always seem to get one that doesn't come out well.
