Produces a very uniform neck and neck tension. It is traditionally used for a bolt gun where you can get by with neck sizing only but I have found it to improve brass even when full length sized. I use it on fresh home made blackout brass. Cuts groups size in half.
Yes sir I know what it is and how it works. Lee just has too much of a bad track record with regular grendel dies for me to get a collet die from them.
As I said I wish this project lots of luck and will follow along and see how it turns out. I will just have to pass on it is all.
