I'm down to 223,260,and 7mag. Not that I really need the 7, but it makes me feel warm and fuzzy.
With a 6.5-06AI, .280 Rem and 7mm RM, I really feel like I need to plug the holes. Just can't figure out if what I need most/next is a .264 Win Mag, .270 Win, .270 WSM or WBY, 7mm-08, 7x57, or .280 AI.
Or maybe a 7mm Rem Express or 7mm-06 ...
(Full disclosure: Actually, a Ruger #1 in .45-70 is highest on the list and I don't plan on that any time soon.)
