Jim Schockey boasts 1000 shots w/o cleaning. BS, also it is the only powder he will put his name on, does he really use it? and would he have his name on the powder if he wasn't being paid? I don't believe any of the boast of these professional hunters I decied for myself. It's amazing how many people fall for this sort of BS, You have done the right thing in inquiring about the powder. Stay with 777 loose, 100 grains. the pellets really only have about 130 grains in them, they are not true 150 grains because of the liability aspect. Cause I'm sure Traditions and such would have pressure problems, maybe not in all but it only takes one to blow if your the one behing the trigger. Just check and see how many law suits are being drawn against CVA. Don't get me wrong Traditions and CVA are probably good guns if kept at proper pressure limit, I think they are rated as 10,000 pund for thier barrels. Be sure, Be safe
