t/c 56 cal smooth bore and minie balls.
Reaction score. 2,160. Location. SE CT. Feb 7, 2017. #8. My experience with the T/C .56 is different from yours. With a .550 ball, .015 mink oil lubed patch and 80 grains of 2f, I get four inch groups at 60 yards, which is as far as I usually see deer here in the dense laurel of southern CT.
