Bull Plate {or whatever it is called} for Sprue?

[340six]

Does this go on top the sprue so the lead does not stick?
I also read someplace that Marel Mystery Oil would work just not as good.
I had a devil of a time ladle casting till I realy got going.
Also the sprue on my lyman 452389 kept getting loose as it open and closed has a bolt.
Is this whats used also on my RCBS 45acp rn mould as well?

Under the sprue plate. and on top of the blocks on pins and hinges. Good stuff.
Heres the link with the info you need to use it correctly , see top of page 2....Buck

Some folks here on recent posts, tell of using it in barrels as an enhancement to barrel slickness,
and remediation of minor leading issues.

Never tried it for that, bot it works great on sprue plates and alignment pins and bars.

+1 on the bottom of the sprue plate, it won't hurt to swab the spre holes also, just wipe off excess....WFM

I believe that you're referring to my post. In response, YES, it does seem to help in eliminating leading when used as a bore cleaner.....at least for me it did.
