Just finished my first rifle build, 22 creed on a kelbly nanook action, proof 22” sendero contour, alpine hunter stock, trigger tech diamond. I ordered 100 alpha brass and a set of redding bushing dies. I bedded the action with gray marine tex. I plan on shooting Berger 75 grain vld’s with H4350 for coyote and groundhog and just plinking. Should I fireform 50 of them before getting serious with load development? I don’t have a mandrel or any way to expand the necks. I couldn’t wait to shoot it so I loaded up 10 rounds with 39gr powder and .020” jump and got a couple 3/4” five shot groups. What’s everyone else doing with new brass before load development? Am I overthinking it?

I wouldn’t size any until the whole batch is ready to be treated as one. Keep the stuff uniform where you can. My fired alpha didn’t grow appreciably from virgin with my chamber.
Shoot what you want for plinking but I’d start some minor load and pressure testing myself.
