Hi, I've got two Marlins I'm considering switching over to cast. Both have Microgroove barrels.
M336C, .30-30 Winchester, no idea of bore diameter.
M1894CS, .357/.38 Special, no idea of its bore diameter either.
The molds I have for the 1894 are handgun--RCBS 150 SWC, which works very well out of an M586 S&W, and a Lee 158 RNFP which has not been tried on anything yet.
The molds I have for the 336 are an Ideal single cavity marked "308291" "52" and an Ideal single cavity marked "154 GR" "896" "308241" These two molds have been bead blasted down to bare metal. Both are plain base.
Thanks. Any advice or recommendations will be appreciated.
