I got tb initially to try with guard rounds in 30-06, but finding American select, bullseye, and others are getting great results.I had 3 x 9 oz flasks, and it did OK at pa-tink velocities in 38, 357, 44 Mag, and 45 Colt. It's decent, but so are 231, and the Alliant shotshell powders I grew up with for 50 years+.
