After the last Lee thread I started thinking about thier rifle dies. Years ago I did a side by side comparison between Lee and RCBS dies and found the RCBS to be more accurate, so ever since I bought RCBS dies if accuracy was a major concern. But I never did examine them to see if their was any room for improvement, until recently, and I think they may have some potential.
I happened to have a few pieces of 7.62X39 brass on the bench that was all prepared except primers, powder and bullets, so I took half of them and loaded them with the dies as is, then modified the seating die and loaded the other half. I don't know if I'll ever get to shoot these but I did check them with a Sinclair concentricity gauge and noticed that the amount of runout was a bit less, and much more consistent, after the modification.
Before I get my hopes up too high I'm going to pull out a larger pile of some other caliber to see if I can get the same results, and hopefully even shoot them.
The modification was to the seating die only. The bullet seating plug is very loose, which they seem pretty proud about, but I'm thinking it needs to be centered and with as little play as possible. I used masking tape to correct it for now, but if it does work I might have to look for something more permanant.
So, has anyone else experimented with them, and if so, what were the results?
