Now 45 grains of Pyrodex RS, which borders heavily on a compressed load, behind a 180 grain Cast bullet for 4 loads.

Average velocity 490 m/s with the 4 shots in a vertical column with a max separation of say 4". Actually the other 3 were clustered on the top right corner of the bullseye with one outlier down below. Boy that Pyrodex RS really colours the cases. Having a slight issue w/ stuck cases.

Cheers,
