After a 25 or so year break I'm going to cast some bullets. getting a new Lee 6 cavity 175 grain TC mold and handles for the 40 cal.

Any advice on breaking them in would be apreciated.

soap and water

If you dont tap & thread in set screws on vertical pins, it will fall apart.

Drill and pin mold wooden handles.

you might want to review this article:

It cover more than you really need to do but if you do have any problem this will provide a "fix it" answer.

I use a screw instead of the nut to lap the mold and I use Bar Keepers Friend or BonAmi instead of actual lapping compound. Usually only a few turns are required to get the bullets dropping out by just opening the mold. I never need to smoke the mold after lapping.

As was said be sure to thoroughly clean the mold before using. [/quote]

if you read all castboolit, you'll find soap and water. no smoking of molds fro professional casters, Thats the way i went. A lee mold is to poor of aluminum to lap. Best thing with lee mold is leave it alone, but its gotta have set screws. If you cast 2000 a year, leave it alone. If you cast 1000 a week buy a NOE or lyman steel.

I do agree that serious lapping of a Lee molds can lead to a ruined mold.

If using BonAmi or Bar Keepers Friend it not really lapping as much as it's smoothing out any burrs that keep the boolits from dropping with out rapping the mold handle's cross over nut.

Today Lee seem to be doing a much better job with their molds. But I have at least 5 that required Bar Keepers Friend to make them function as well as my Lymans, RCBS, LTB and others.

I also like the new Lee molds pins much better than the old tongue and grooves.

Molds are soposed to delivered tomorrow. Today at 3 PM I had 103 degrees. I'm not going to be firing up the lead pot until these temperatures change.

My lead pot is a home made bottom pour natural gas fired, holds 30 pounds. Took a quick look at it a few days ago, think all I have to do is put a new hose on it.
