I like the strength of it, but as mentioned above it tends to recoil a bit more like a CF than a muzzleloader. Started with 3F loose and quickly reached the conclusion that granulation is just TOO hot. Using 2F seems a lot more forgiving to the big conicals I like to shoot. I' ve come awfully close to just throwing my hands in the air and going back to loose Pyrodex P.
My experience with other powders has been similar to yours. Sure there is fouling, but not like the ring of fouling from T7! And I' ve found no way to avoid it so just swab after every shot. Sometimes just a damp patch and sometimes a damp patch over a brush followed by a dry one or two. It' s a pain on the range but the powder is consistent. Some say putting a dab of bore butter on your sabot helps to keep that fouling soft. The only sabots I shoot are a royal pain to load and though I do add a touch of bb to the base, can' t say for sure that it helps anything.
Herman, as a little aside - don' t know if you have seen it or not - but I think Cecil Epp may be onto something as far as using 209 primers. His article on modding the Encore breech plug is interesting.
http://www.prbullet.com/hornet.htm Seems kind of extreme. I think RWS, CCI, Federal, Rem, Win, yadda yadda ought to get together with the muzzleloader manufacturers and tool up for a " muzzleloader only" primer of some type that would incorporate the gains of the 209 without the attendent problems. I' m sure they are concerned about my opinion.
And, his improved Super Jags look good. May have to order a couple of those.
