Quoted:
I'm working on my first batch of .223 reloads.
I'd like to get to working up precision loads for my 18" AR, but I want my first batch to be plinking ammo. That way, if I screw up (as I have already), I only ruin cheap components.
I have a Wilson case length guage. My question is: should I try to tailor my first batch of loads to the chamber, or just size my loads according to the min/max specs from the chamber guage? How much effect will that have on accuracy?
ETA: for this blasting ammo, I'd like to be able to shoot it in any of my ARs. I'd really like for all my ammo to be interchangeable between the guns.

If you mean Wilson case gauge, use the gauge to set your sizing die.
Adjust die so that the end of the sized of case is below end of gauge, but above the cut.
The cut is .002 deep, so it may take some trial and error.
After sizeing 2 cases that "gauge" per above, wipe off lube and chamber in your AR.
If they fully chamber, (sized case, no powder, primer, bullet) you will be able to hear a click when you pull the trigger, then see if they extract easily.
If they do, your sizing die is set correctly.

If not, report back. Good luck.
