Re: die preference?
For myself, I do three types of reloading.
Handgun, rifle plinking, and rifle "business" type.
Handgun for me is medium volume, medium precision. My handguns digest everything I push through them, including cast bullets from wheel weights.
Rifle plinking is high volume, moderate precision. I choose powders for the combination of accurate metering and accuracy results. I won't be winning any long range matches with this stuff, but it's fun, and we burn through a ton of it.
Rifle "business" is the handcrafting each round, scaling each charge individually, seating to the exact same COAL every time, using trimmed and neck turned brass.
Handgun and plinking ammo get RCBS standard type dies.
Business Rifle ONLY gets REDDING dies.
I'm not personally sold on the micrometer seating dies, but then again, I only used one for about 50 rounds.
I felt I got similar results and consistency with the standard die, though the mic was a little easier on my fingers.
YMMV, but make no mistake, I LOVE my Redding dies.
