[QUOTE="KsKevin, post: 2479884, member: 116689"] My 280ai loaded rounds run about 0.3105 - 0.3113” (nosler brass bought about 8-10yrs ago, measured using mitutoyo mic). I use Redding bushing dies and run 0.307 neck bushing without depriming pin expander ( springs back to about 0.308”) then mandrel expand using 0.2825 pin (from 21st Century). Outside of necks run about 0.3085” before seating bullet so gives me about .0025” “neck tension”. I don’t have any Peterson 280ai brass but have heard the same as others have mentioned that it is a bit thicker. QuietTexans data of 0.312-0.313” OD with Peterson I would think you’ll be covered with the bushing range youve ordered and suspect when the dust settles you’ll land using about 0.309” range. Best wishes with your new incoming 280ai. I love the cartridge (have a GAP 280ai and currently in-process of building another one with ETA of Aug assuming stock arrives in July). [/QUOTE]
