What kind of rifle are you having trouble with the No Excuses Conicals? What kind of powder charge are you shooting? What is the twist rate of the rifle? I have three different inline rifles and as long as I keep the powder charge around 80-85 grains they shoot great. Also what kind of powder are you using. If you can get your hands on some Pyrodex P try them with that. The conicals seem to like the Pyrodex. I am currently out of Pyrodex P.

In my CVA Staghorn I shoot 80 grains of Goex 2f. In my Knight Wolverine II I shoot 80 grains of Pyrodex P or 85 grains of Goex 3f and in my Black Diamond XR I shoot 80 grains of Triple Se7en FFg and the accuracy in all the rifles is excellent.

I got terrible accuracy with Pinnacle Powder for some reason. I forgot to try the Clean Shot with them, and then I ran out of them. The wads might make a difference. You can buy them on line but it is much cheaper to make, although the store bought are easier to use I think. Get as thick a felt as you can find.....

Good luck
