I picked up four pounds of Norma 203-B from Powder Valley with the intention of using it until I can get a good supply of IMR 4064. The first 50 rounds of load development were not impressive but not to be deterred (Cause I only used half a pound and I don't know what else I'd use it in) I played with the seating depth of two of the charges. The first group I shot put four rounds in one hole and one flyer that brought the group to just under an inch. I'm pretty impressed with this powder. The load was 43.2 grains of 203-B behind a 168gr CC with a CCI 200 primer and 8X fired Lapua brass.
