Any thoughts on must have "Lee Moulds" as good shooting rifle bullets

[Rcmaveric]

I’m going to try the never sieze. I have a couple of the Lee 7/8 oz slug moulds that are self destructive. I have a Beretta that likes them, and it makes neat holes in snobanks.
I cast 22 lbs of numer 4 buck a couple days ago. It drops them in strings of 3, 18 per drop. Without a doubt the hardest mould to keep up to temp. I add tin and run the pot at 800, fast pace and two pots to keep recycling the sprue. Too low of temp and the shot look like turnips. Needs a little pressure directly in the hole also.

I have the Lee 1oz slug mold inbound and the .311 RB mold inboud to use as buck shot (I am cheap and its 20 bucks vs 60).
