MICHAEL, from some of your previous post, i really don't think Barnes or any other bullet is the problem. as LEE and Sabotloader and others here have told you T/C rifles are tight barreled, some more than others.have you ran 50-100 strokes of JB down your bore yet? Sabotloader had your same problem with his triumph and now can shoot Barnes,gold dots,lehighs and other bullets with accuracy. a bullet is nothing if the sabot is to tight or to loose.as far as powders are concerned i have shot pyrodex and 777 and 777 wins hands down.my BH 209 didn't make it here this past weekend with my friend who was supposed to bring it, but by all accounts it is a excellent product also.if you haven't already, i would try 100 strokes of JB and test the rifles again.Wakeman didn't give the triumph very good reviews for balance and a few other things, although accuracy wasn't a issue in his review.i bought it based on real world everyday people reviews of accuracy.dependability, weight and price. Ray!
