All work about the same, with commercial being the least tacky. Bullets MUST be cut out while the lube is still warm, and a bit of experimenting will show you when the time is right.
Blue soft can be wiped into the grooves with a bit of lube on the index finger of the master hand, then hold that finger out of the way as you use that hand to push the bullet through a Lee sizer, or seat into your ammo without sizing. I find finger lubing far less messy and much faster than the cake cutter method, having loaded thousands of rounds this way. When I do it, I visually inspect the bullet, apply lube, only in the last groove for lighter loads, and seat the bullet. It goes supprisingly fast with little bullet handling. By the way. Don't get caught up in weight sorting bullets. Learn to cast with high quality and shoot everyting that drops from the mold if it looks good. In my book, Jacketed Performance with Cast Bullets I go into good detail on the reasoning behind all the above. You can purchase the book from LBT for $30 post paid in the U.S. (2006 price)
