I poured a few C312-155-2R for the 300 BLK today. It was my second time using this mold and I’m still feeling it out.
I used a cobbled together “hardball” alloy of 25% Lino, 25% spacer strips and 50% cable sheath. I know the spacers could be most anything, but this batch snaps when folded, so I figure there has to be some tin and antimony in there. Regardless, the resulting alloy casts beautifully and makes boolits right on the nominal 155 grains. Kept the pot at 700-725 and the fill out was sharp and the sprues cut smooth. Even at the low pot temperature the boolits would start to frost and I would have to touch the mold to a damp sponge occasionally.
I really enjoyed this session. I needed to turn my mind off and concentrate on simple things for a bit. It’s a shame the arthritis is making the sessions shorter, but thank God I can still cast and shoot. Many have it worse.
So that’s it. Nothing really notable here. Just happy with the day and posting to talk to like minded people.
