I like Reddings profile crimp for some applications. But know its a ROLL style not a taper crimp. YES it tapers some as well but rolls making it not a taper.
IMHO LEE made quite a dumpster fire of crimping dies.
When they came out with the FACTORY CRIMP DIE. It did solve one of the biggest problems new re loaders had. Crimping and seating in one step. Also the design if the die is not case legnth dependant. Its a collet style crimp.
Then they started calling taper and toll crimp dies FACTORY CRIMP dies thoroughly fudging up the works.
