Hi, I'm brand new to reloading, and I wanna start reloading .223. I have a whole bunch of range brass and I'm wondering if I resize them all with the same resizer die (and setting), will they all pretty much be at the same headspace reading? Or, will they all be bumped back BY THE SAME amount, but still be different? My hope is that I can resize them all to a standard headspace reading and I won't have to check each one with a case gauge. Then I can trim to a standard length, and they'll then be somewhat consistent. This is just for AR-15 plinking ammo, so high precision is not necessary. Just high reliability and safety!
