I bought an A-Bolt Hunter in 1992; it's been my go-to rifle ever since. I just had it out this morning trying a load of the Barnes 145 LRX over H4831; it shot pretty well and will likely get the nod for next month's moose hunt.
It's become a lot more popular than it was, and rightly so. Dave Petzal, shooting editor at Field and Stream, said this, and I agree:
"** .280. ** Along with the .270, it combines more killing power with less recoil than anything else I can think of. There is a huge variety of bullets available, but for deer, the top one is the 140-grain. For some reason, the .280s I've used have been fussier about what they ate than the .270s. For the one-gun hunter, the .280 is a top choice."
