I have used LEE molds for over twenty years. I would hate to think how many .50 and .54 caliber roundball I have cast out of them. And I cast the LEE REAL in .50 and .54 in both weights. They are still holding true.

I do leave the last projectile in the mold when I am done, and let it cool with the mold. I was told by an old time caster that it helps the mold from warping. Whether it does, who knows.

I have tried the REALs in slow twist barrel and discovered they did not shot well. They seem to do much better in the 1-48 and faster twist barrels.
