Thread: Issues Seating Cast Bullets

They are the same price it seems, lee could be used on other cartridges in the future, but I don't plan to shoot any other cast bullets so not a huge advantage to the Lee.

Although I have never used the Lee Expanding die I think it would be the better bet. I have several Lyman M dies. In 30 cal they expand a section of the neck to .308 ie put a step in it. With your gas check at .311 if an M die was used there would still be some resistance when seating into the start of the neck. The Lee die is different to the M die in that it flares the opening to whatever you need.

I see Gunworks have the Lee. Availabilty of the Lyman probably not so good.
