I like my LEE 20lb pot. I use a thremometer and the temp stays set pretty good. It drips a little but not enough to really complain about. I'll try the added weight thing, maybe it'll stop the small drip, I messed around with the adjustment and never really had any luck.
I load, 9mm Luger, 38 and 40 S&W, 38 Special, 357Magnum, 45ACP, 45 Colt, 223, 300 AAC, 243 and 30-06
