Thread: Reloading 38/55

Reloaded some of the above with ADI 2206H, 21grains, 1100 FPS, replacing black powder, to much fouling in small calibre.
On firing have residual unburnt powder in barrel? Take it I’m getting primer flash over and not enough powder in the case? So either change to say trailboss for more bulk or put a filler in to hold powder against primer? Using small lubed lead projectile, about 250 grain.
