There isnt to many products that make me kick myself in the but for not finding ealier but this is one! Its called bullshop mold lube and its mostly made for lee alum molds but will work on any of them. Ive been using this stuff for two days now and to me its about a miracle lube. It makes a lee 6 cavity mold run like glass, doesnt contaminate the cavitys and prevents lead for sticking to the spruce plate and top of the mold. Im one that can ruin a lee mold in one session and ive been using it on 4 new 6 cavity lees and the stuff just plain works! Its cheap to buy and a bottle of it would probably last the average caster forever. http://bullshop.gunloads.com<!-- Message body ''"" --><!-- Message body ''"" -->

You have my interest Lloyd Smale. I gotta say up front that I have not had trouble with my Lee multi-cavitity molds to this date. Mine cast good and dump bullets "hot and frosty" just fine.

Good tip for those that are having trouble?

Cheezy, you don't have to be having trouble with a mould to appreciate it. It makes ANY mould perform much smoother, and works so well, that you can cut the sprues before the puddle in the trough is fully hardened, eliminating any "torn" bullet bases and results in a smoother, nicer, bullet base. AND it is dirt cheap. It looks like a win/win situation to me!

... you can cut the sprues before the puddle in the trough is fully hardened...
You're not supposed to do this. The lead in the bullet cavity shrinks as it cools, and draws lead down from the sprue. If you cut the sprue too early, the bullet will draw air instead of lead, and you'll wind up with a hollow bullet.

:(

I don't cut it when it is still liquid, just before it fully hardens. I agree that the liquid in the sprue is sucked down while the bullet cools, and is important for fully formed bullets. I periodically weigh bullets to ensure thier uniformity, and they are just fine.
