I have read other reports of this kind of problem using American Pioneer Powder. People get jugs of bad powder. First thing I would do is contact the company and advise them of this. It would be interesting to hear their responce, and it better not be, well just take it back to the store and get your money back or new powder, because I would tell them where they could put my next batch of powder. I would want to know why their powder went bad. Especially if this was a new jug the pellets came in. You're right, it does not give someone a lot of confidence. If I'd been waiting all day for that shot at a buck and then have a misfire because of the powder.. well needless to say I would black list that stuff real fast.

Triple Se7en is not a dirty powder. That never has been a complaint with the powder. The big complaint with Triple Se7en is some rifles form a hard crud ring when they shoot it. If you swab properly this is not a problem which obviously you do. Also for consistant shot after shot and power, Triple Se7en is hard to match. I think you made a wise move when you decided to stick to the Triple Se7en.

Some people have excellent luck shoot APP. I have personally never shot it as it is now called APP. I shot a lot of it when it was called Clean Shot and in loose form was one of the best powders I ever shot.I liked it so much, one side of me wants to buy more and then the other side reads posts like this and says.. stay away from it.

Glad to hear your rifle tuned in so well. My CVA really does a great job with the 245 grain Aero Tips...
