I'm one that cleans between each and every shot...I dampen 2 patches with rubbing alcohol, run down the bore, both sides, then a dry patch, a slightly oily patch and another dry patch....

My load is 90 grains of Pyrodex R-S behind a T/C 250 Shockwave...I am sighted in 2 1/2 inches high at 100 yards and I'm about 2 1/2 low at 150...Hope this helps...Have fun...
