I got my 434250 6 holer all debured. A smidg of lube and I was heating her up.
For two hours of casting last night, I got 8 boolits that I could keep. This is a known good alloy. I got the mold hot and still couldnt get any full boolits.
So today I broke out my little files. I cut a slight grove between the cavitys on one block from top to bottom and did the BruceB vent line tracing to them on all cavitys.
I Gently removed my filiengs and tryed again.
6 for 6 right from the word go! All the well filled boolits fall from the mold with ease!
The only bad part is this alloy starts out dead soft and takes 3 weeks to get to the 14 BHN I shoot. Kinda pain but I got a bunch of this stuff cheep and it casts well.
I could have water droped but I have to put the finishing touches on my last project first anyway. ....Buckl
