RE: Need best caliber Opinions.
Would you go golfing and take one "all around" club? $ is always a consideration but trying to do everything with one gun never really works too well. When they brought out the .22 accelerator sabots for the 30/06 it looked like the solution had arrived for the fellow wanting one gun for big game and varmints. From what I've heard and the fact they never caught on, it didn't work out.
I have never owned or shot a .280 but have always liked the look of them on paper. I shoot a .264 win. mag.
