Hi.guys, yes I think your best bet is a lee mold, 170/80g, but cast with wheel weights or lino type, the 3030 has a fast twist rifling and soft lead could lead up the barrel . All so a round ball needs a slow twist, 1 in 48", but mite be ok with a light load of 30/40 grs of fffg, Still be hard to get the bullets in, good luck, Homebrew.357.
