I've been researching this problem and keep coming up with nothing. I have a lyman 225438 mold that just seems to be the devil. I cant get it to cast right at all. First it was casting undersize, then after reading up on "beagling" I turned out a brass blank and lapped the drive bands to the size I had hoped for. Then I was having problems with boolits sticking in the mold, to the point a pair of pliers and careful pulling was required. I found a few threads on deburring and polishing the mold. That was my next step. Now she shines and drops great! But then another plague hits. My question and point to this post is this: Has anyone ever experienced boolits casting oversize on length. I tightened down my sprue plate and I still get some overflow up and boolits started sticking again. It seems the lead is flowing under the plate ever so little, just enough give a tiny lip and stick the boolit hard in the mold. I had purposefully cast for rounded bases and they drop right out. Then when I cast for full fill out they stick. I've tried hotter mold cooler alloy and hotter alloy cooler mold and just about every combination. This is my first small diameter cast, everything else has been larger pistol and some 30 cal stuff. Never ran into this problem before, has anyone else? I'm using lyman #2 from rotometals and currently trying to keep mold around 300 and alloy under 700. This gives me great fill out, but sticky boolits.
