well , i just got an email that after 2 months .. my lead bullets are shipping!!! so, now i'm waiting for my bergera barrel to arrive as well... anyone has a good recipe for these on 16" barrel 8 twist? i assume a lead bullet will be slicker than my usual 220 smk and probably will require less powder ???
anyone with load data , care to share ?
thank you!!!
