Lock and load with your PRB and go forth to hunt. Listen I had killed about 20 deer with a 30-06 when I decided to try black powder. I got a TC Hawken and figured, if the round ball was good enough for Davy Crockett I would give it a try. If it did not kill well, I would try some maxiball and if that didn't work, I would just go back to the Mauser. There was no BP season in Ga at that time so I was just doing bp cause I wanted to. I was amazed at the killing power of the round ball. On a lung shot it kills better than a 30-06. I use a .490 ball with .015 pillow ticking and Old Zip patch grease from Dixie, it is a combo of mutton tallow and beeswax. On a 150 lb Ga. deer at 70 yards on a lung shot I expect the deer to go 75 or 100 yards when hit with the 30-06. With the round ball I never saw one go over 50 yards. I shot 7 deer and 5 more hogs with round ball. I liked the work of the TC so much I bought a Tenn. Mtn Rifle from Dixie, I used the same load. Also, 80 or 90 gr FF Goex, both charges work ok in both rifles. When hit with the round ball all 12 balls exited the animal. The blood trail was phenomenal, better than I ever saw with a 30-06. Often, with the round ball, it looked like you had a 9 year old boy, and you handed him a gallon of red paint to hold in each hand , with the lid off, and told him to run find the deer, and you followed him. Easy blood trail to track and you know there is a dead deer at the end of that trail. I made a blanket from 4 deer hides and it is warmer than any rayon. I built a log cabin with dovetail notch logs. It is warm and snug. Davy Crockett wasn't so dumb.
ps I have never had the powder get wet from this patch lube. I have left my rifle loaded for 2 weeks, no problem. Don't know what Davy used, probably bear grease. If I were buying patch lube today I would get Lehigh Valley, it is very good.
