Anyone heard of or use Rooster Zambini lube? Any good?

I dont cast yet... But the guy I last bought bullets from says he uses this stuff

Sounds like ky jelly for perverts.

It’s a hard lube and you’ll need a heater to apply it. It works fine for my needs and I don’t have any complaints about it. It’s not a black powder lube, just smokeless.

The real question is, if you shot the guy’s bullets how did you like it? Your shooting experience with the lube is the only thing that really counts.
