For a long distance target rifle, that I may drag out to hunt with occasionally.
Thinking 26" bbl Varmint contour for either.

I already am set up for 6.5x55 asI have a Swedish mauser and I like the dimunitive recoil, but 280 would make a better hunting round.

That said I also have a 7mm mag 24" sporter barrel if I really need a long distance 7mm thumper like for Elk etc.
