Just curious, how do you define full length size and be done with it for a beginner? That's interesting and I'm curious why you describe a critical part of rifle reloading that most beginners don't understand so casually.
$450 for a lifetime tool that makes loading every volume ammo caliber a breeze is a small investment, what 22.50 a year for 20 years? The span of reloading for good gear. Then again, if plinking mean loading a thousand rounds a year of 223 then maybe you are right.
To define "full length size and be done with it" I'll refer you to the instructions for the sizing die and almost every reloading manual ever written.
Size it until the die hits the shell holder is a pretty simple and fool proof method.
See, your reloading is way beyond normal and I think you forget that sometimes. I doubt 75% or more reloaders even load 1k rounds a year total. You do that, what, before your first cup of coffee is gone?
You wear out pro level tools. Most rookies will never wear out entry level equipment.
