I urge you to try Dick Dastardly's BigLube bullets. You can buy them or cast them yourself. They have a HUGE lube groove that eliminates the problem with the Lee bullet. I've had great luck with mine and shoot almost nothing else. I use no wad or lube over the bullet and I shoot soft lead. I can shoot endless strings without any leading at all. I shoot very hot loads of 45gr of Triple Seven in a deepened ROA cylinder as well as a Classicballistx cylinder (which is better than Rugers!)
