Them boolits is too pretty to shoot, almost.
Do you need a set of forming dies, or does the FLS do it? How heavy are those little jewels?
Size die does the trick but the 1/2" that gets choked do need a splash of lube and annealing helps a bit. 183 gr of 30:1 alloy from a Brooks mould. They cast at ~.3095" and I size to .309. Dilute ALOX lube and dusted with mica/graphite mix.
12" twist 19" barrel from Bullberry, Silencerco Octane 9 can.
The expander on the die is tapered, .308-.310" and the seat die does a tapered crimp
I figure pretty bullets try harder.
