close to 200 .223 1x fired mixed brass out of the 783.
learning about neck sizing with a Lee collet die. full brass prep on these, and primed, ready to load.
Going to go thru a few different powders. Will try Varget, 3031, Benchmark and TAC. Probably not too much testing with TAC as that seems to be better for light weight bullets and this rifle will be more for 68-74 grain pills.
