Back to the original question. If the rifle is priced well I would get it. Have a look with a bore scope first. If dies come with it then better still. If you want to shoot 243 for awhile you will loose only around 40-50 fps in most cases.
Target shooters especially with hot or double based powders like R17 or VV 560 and running heavy VLDs at maximum velocity will loose target grade accuracy in as few as 1,000 - 2,000 rounds. Hunting accuracy could almost triple that.
Only if you did a lot of varmint hunting or target shooting would you burn out the barrel in short order.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
