Lube grooves vs single groove

[mikedp]

I tumble lube my boolets cast from my Lee 356-120 mold, but they don't have the tumble lube grooves that other TL designs have. Seems to be working for me OK. Are there any disadvantages tumble lubing these single groove boolets?

Should be fine. My 358429's get a coat of BLL, sized .358, and then another coat. Works great in .357 Magnum.
