How true Lewis, I don't have access to real long range areas but have done a lot of shooting at the 200 - 250 yard range. It sure builds confidence for those lesser ranges.
I know this is not muzzleloading but I'm only using it as an illustration. I've read a lot Elmer Keith's writings and like many, I scoffed at his 5-600 yard shots. Well one week when all the shooters at muzzleloader league got done shooting 200 yards a friend asked if I would like to try his 45 Caliber S&W mountain revolver. Never shooting that distance or that gun before I was able to hit the 16" gong 3 out of 6 shots and this was totally free hand, made a believer out of me.
