Is this limited to just subs, i guess it is since its in the "black powder" section.

BH209 when its on sale for my inlines with a Lehigh conversion.
Swiss for testing in my GMB54 with conicals.
Im trying T7 again just to see if ive helped the crud ring issue by following Sabotloaders advice.

Im avoiding Pyro just because it is at least as corrosive as real black and it creates some cyanide laced byproducts when fired.

Otherwise its 5744, N110, N120 and Re7 (IN APPROVED GUNS). Almost no cleaning needed and ES is excellent. Plus its way cheaper to shoot than BH209.
