You can reload, and I suggest you do so. There are a ton of high BC 6.5 bullets out there now. Use Fed 215 primer, Neck size the brass (for more brass life and better concentricity) , Try slow powders such as Retumbo, US869, or even H1000. Once you get yourself set up with supples and find the right load, you can load for about $1.40/round. Not bad for the baddest 6.5 on the planet.
You have a Vanguard, which means your gun will most likely be a very good shooter out of the box. As far as barrel life, if you take your time and let the barrel properly cool in between shots you will definitely see prolonged barrel life. (I usually wait 3-5 minutes when its cold and 5-7 minutes when its warmer) If you look closely as to the terms of decreased accuracy vs. "shot-out" barrel you will discover the 2 are entirely different. For this caliber, normal decreased accuracy will occur around 1,000 - 1,200 - rounds. Now this is where the argument may start. This can simply be going from a sub 1/4" group to a 1/2"-5/8" group for a reloader, or it can mean going from 1" to 1 1/2" for a box ammo guy. I know a guy shooting sub moa with a 30-378 after 1,500 shots with factory barrel. Why? because they never shot rapidly to the point where you can light a cigarette off the barrel! All in all, barrel life / performance all depends on how you treat rifle and what you perceive as being accurate.
*This is from hand loaded 140gr. berger @ 3375 FPS* Recoil without a break is snappy, but nothing that is unmanageable. With a muzzle-break, its comparable to a .270.
Some may argue with me here, but I'm a bit old school with my logic - You should have proper bullet expansion velocities and the proper knock-down power for a proper and humane kill (~1,200 lbs/ft. for white tail and ~2,000 lbs/ft for elk).
1,000 + yard paper puncher / steel plate gun = yes
650 yard and under Medium Game gun = Yes
450 yard and under Elk gun = Yes
To sum it up, if you want to be a part of the 6.5 LR crowd and actually have a cartridge capable of being very effective on game at extended range go for it. You have the Ferrari. If you aren't looking for a rifle with laser beam trajectory or the ability to put down game DRT at extended range, save your money and go with a 6.5 creed more.
Go where others refuse, but do not lose your common sense along.
