I just picked up a T/C Seneca in 45 cal. My day was kind of cut short due to rain, but I did manage my best 50 yard offhand target to date. The load was 70gr of FFg, .440" Hornady Round Ball, and a .015" patch lubed with Greased lightning + water. The the bullet hole far right was my 1st shot (choked or dirty barrel). I cleaned barrel (had just shot about 10 shots at 25 yards) and then took a 3 shots. I couldn't believe my group at 50 yards shooting offhand. My best to date 50 yard, Offhand group to date. I was shooting one ragged hole at 25 yards, but I was not expecting this at 50 yards. With all of my Green Mountain barrels I wasn't expecting my best offhand group to come with a Seneca 45 cal I just bought! I'm sure it was just a fluke, but I will take it
