I have tried Blackpowder,Pyrodex,Black Mag,Triple 7,American Pioneer Powder,Jim Shokeys Gold,Clearshot,and White Hots.
All of these sub powders had some problems or drawbacks.
Tried Blackhorn 209 on Tues in 3 guns.
Knight Disc Longrange Hunter.
In all three guns no swabbing for the entire range exercise.
Loading seemed to get easier after every shot.
The Huntsman never grouped tuesday it grouped three shots touching at 50 yards and almost touching at 75 and 100 yards.
The breech plugs were updated on the Knight and NEF to use the Blackhorn 209 powder.
Omega used standard TC plug.
Sabots used were the TC black with 240 grs. Hollow point Hornadys.
90 grs by volume.
Cleaned 2 guns last night [friday] no rust,shooter choice solvent 1 wet patch followed by 2 dry patches no brushing,
Omega being used this week for hunting may clean in 8 days after season is finished.
Breech plugs removed easily and were very clean.
No crud rings at all.
