Interesting how we piece together die sets.
For my 25-06 I use a Lee Collet Neck Die or a Lyman FL Size Die, a Redding Body Die and a Forster Ultra Seat Die.
For my 223 I use a Redding FL Size Die, a Forster Ultra Seat Die and a Redding Taper Crimp Die.
For my 221 Fireball I use a RCBS FL Size or Redding Neck Die and a C-H Seat Die.
For my 7mm Rem Mag I use a Lee Collet Neck Die or a Redding FL Size Die and a Redding Seat Die.
For my 45-70 I use a Hollywood FL Size Die, a Lee Powder Through Expander Die, a Vickerman Seat Die and a Redding Taper Crimp Die.
The only cartridge I load where I use a single die manufacturer is 40 S&W pistol and I use the Lee set with a Lee Classic Turret for that. I'm pretty much color blind but you will not find Hornady dies or other Hornady equipment on my bench, bad experience that I don't care to repeat. Never ventured into the Dillon world as I do mostly rifle.
