Last night I was casting some boolits and said what the heck, I'm gonna try something a little different. Don't get me wrong, Bullplate lube is great stuff and I'm not knocking that product, (I have 4 bottles myself) and will continue using it.
I got out a bottle of 2 stroke motor oil and applied it to my Lyman .430 swc face and under the sprue plate. I cast around 100 boolits and was cutting the sprue rather quick to see if it would smear lead across the face, guess what...it didn't smear lead anywhere. I gonna give it another test run soon and will post the results, so far I'm impressed./ Ron
Yep it works and the synthetic is best

Does it still leave a dimple from cutting it too early?

You mean a "divot" or "tear out" from not being solid enough?
I'm going to try 2-cycle today just to see how well it works.
I alreasy put Kroil on all my molds, one more "additive" can't hurt!

Don't get it in the cavities. Do some research on 2-cycle oils, you'll be surprised at what you find.

Lee recommends silicone spray, and that's what I use.

I had a old bottle that is all but empty so I thought I'd give it a try. All I can say is I am very glad I did I'm quite pleased with the results
