Anyone have any experience with one of these? I will be starting to reload .223 (again) since I will be picking up my new (slightly used) H & R Handi-Rifle next week. Anyway a couple years ago I acquired one of these die sets in a pile of reloading stuff I bought and have decided to try it out. I really like how it will align the bullet and hold it nearly perfectly through seating as opposed to standard non-supported seating dies. Anyway if anybody has used one of these and has any input or hints please advise. Thanks.
