Cast a bunch of bullets for my 11.15 X 60R German double and got a box of 20 cases ready load with 5 grs. of SR-4759 under 68 grs. of Old Eynsford 2F. After a fouling shot in each barrel the old 1870's rifle put 6 rounds in 1 7/8 inches at 50 yards. I believe that's good enough for a 140 year old rifle with open sights and 65 year old eyes.
