New gun & Virgin brass load development

[Jory45acp]

I have a new .300BO build and purchased 500rds of new Starline brass. My question is after reading about how load performance changes after virgin brass has been fired 1x should I just plan to load all 500 at once with my current load data for a plinking round, and then go back to the drawing board once they have all been fired and start over with new load development? I'm not loading for match accuracy, this is for 0-100yard max functionality. Any advice is appreciated. Thanks

Why not shoot 100 to work up a load, then reload and shoot them again to see how much you need to adjust from new brass? You could shoot the new brass as you needed to. It would take me most of the summer to shoot 500. Pesky work stuff.

How about work up a load with the new brass and then when you have a quantity of once fired brass tweak the load to shoot well again.

Dont wear your barrel up like that. Develop a load with virgin brass and a load for fired brass. Also, the virgin bug a boo are usually reported by people with other than SAMMI specked rifles. At best they are isolated or occasional reports.
