Depends on your intended use.
# 1. It's a handloader's round. I know that some outfits are loading factory rounds for it, but they're not cheap. If you don't reload, you might think about something more conventional.
For a LONG range target rifle, it's a popular round. It is fairly effective at slinging long skinny bullets at reasonable velocities with moderate recoil. It is especially well suited to a long action rifle so that you can take advantage of both the case capacity and the long bullets, though the parent case was originally designed for a short action rifle. (IIRC the Winchester 88, though I'm hazy on that)
For a hunting round, it's effective, but does nothing a host of other calibers won't do just as well. My sister hunts with one, and pretty well kills anything she shoots, but hers was a special case. I bought the rifle (a customized Mexican Mauser) for her from a man who did not reload. He had purchased it for a song, then found out what what factory ammo costs (at the time, $75 a box from Norma). Knowing that I reload, he sold it to me for next to nothing. Realistically, out of her rifle's 20" barrel, it shoots about like a .260 Rem, if that. If she didn't have me to keep her in ammo, the gun would never be shot.
Far be it from me to discourage anyone from a new gun purchase
, but I think that unless you're going to play the long range target games, you'd be better off with one of the more conventional calibers in the 6-7mm class. I'm a big fan of a 6.5mm bullet, but not necessarily of the 6.5-284.
Some other calibers you might consider that are in the same basic size range, all of which are factory loaded and some are even readily available.
.243
6mm Rem
6.5x55
.260 Rem
Any of the new boutique XTC rounds (6.5 Lapua, 6.5 Creedmore, 6.5 XTC etc.)
.270 Win
There are a lot of others, but those spring readily to mind.
FWIW, I think the barrel burning thing is a non-issue for the average shooter. Not only do most of us never shoot enough, but we won't notice any accuracy degradation until way later than your average benchrester or hi-power shooter. Even 1000-1500 rounds is a lot for a normal shooter through a hunting or target type rifle.
