I’m preparing for a PD shoot. My 222 is a 722 Remington that’s been converted to 700 BDL configuration. I was looking over old notes and saw that my favorite load shoots ~ .3 MOA. I saw on other notes that same load shot almost 1.75 MOA. The difference:
The accurate groups were shot in new Nosler brass. The large groups were shot with 1950’s vintage Remington brass that looked liked they had been shot many times. I suspect the old brass necks were quite brittle, they had never been annealed.
I’ll be annealing brass before I load.
