500 and they don't need to be magnum primers
I picked up a jug of WC820 a few years back, it uses H110 load data. Some of the recent surplus WC820 uses AA#9 load data. I always thought WC820 was either H110 equivalent or repackaged H110 for military use, but I never looked into it.langenc said:How is H110 classed as surplus and what is the cost and source of 'surplus' powder? What other powders are 'surplus'?
