I use Peterson Brass in my 280 remington. Henry at budget shooter supply ordered it for me. It last much longer than Remington, Winchester, or Federal cases and is well worth the money. I also use Starline 30-06 brass necked down to 280. This is probably the best value brass as I got 13 firings out of it before the primer pockets got loose, although I haven’t worn out the Peterson brass yet. If you’re oooking for Lapua brass you can also neck down their 30-06 brass.
