I have a 30/30 TC Contender and have been trying some loads with a RCBS RC kit. A friend showed me this kit that goes against everything I know about loading. It's a Lee Loader. Basically you put a cartridge together with a hammer. He had one for the 30/30. I tried a few rounds. I went from a group of about 3 inches to about 3/4 of an inch. I have done the same (RCBS) for my 7mm Rem Mag Ruger #1. I bought the Lee Loader and today put 3 shots on top of each other at 100 yards. I was shooting eggs at 200. The rifle has had some custom work on it and is accurate but never like this. Anyone else had good results with the Lee Loader??? How about a 223, 243, 30-06, 338???
