"if you hate cleaning a gun THAT MUCH, why you all don't take up Needlepoint instead???"
Except no one was complaining about cleaning their gun(s). I enjoy cleaning my pistols. I don't mind the fouling I get from either Olde E or T7, but cannot stand the sticky fouling Pyrodex has left behind. And then the velocity that Pyrodex is dismal in comparison to either of the powders I use.
My father gave me two bottles of P and one bottle of RS with my Ruger. These were given to him, and he didn't care for them either. So I certainly have first hand experience with them and am not parroting anything.
The velocities shown with your loads were fairly good, but still about 100 fps slower than T7, Swiss, and Olde E. However they were better than loose Pyrodex.
Mr Beliveau got a velocity of 1062 fps with a .457" ball using just 33 grns of 3F T7:
That's an additional 100 fps with 7 grns less powder.
The fouling left behind by Olde E is not hard when properly lubed, and as has been said it may have to do with the lube you did or did not use. I used the same lube when I used Pyrodex and didn't like what it left behind, but then it's likely it's not the same as your pellets, and that may be why you aren't complaining about the residue like everyone else.
As I showed Pyrodex pellets are not reasonably priced compared to the other powders. It's not even close, and to come up with the same number of shots as a can of loose powder you could have paid the HazMat and still had leftover $. This you cannot deny, and for someone who continually brings up the lack of funds you'd think you'd at least give it some consideration as it would do nothing but save you money that can be spent on caps or some such. But that's on you...
