I've been reading where this cartridge can burn barrels out in as few as 1500 rounds.
Anyone have any knowledge as to how many rounds before you have to replace the barrel?

Yep...shot #1501 sets the whole dam gun on fire.

Even if that were true (personally I think its crap) That's 75 boxes of 20. Rifle barrels are like tires on your car, take care of them they last a very long time.

A set of tires for my truck cost more than a decent rebarrel on my rifles.

That has to be a rumor. I had a .243 for 20 years and I probably shot at least 4 times that many round through it.

as ridge runner said, you would have to shoot an awful lot of rounds through the barrel and keep it hot to ruin a barrel. these loads would have to be loaded pretty hot for that to happen. normal shooting wont hurt any rifle.

Thanks fellas, i didn't think that 1500 rnds. would burn a barrel out. I always let the barrel cool between shots and i clean it after shooting.

+1... well said.

My .243 was aquired in 1974. It was a re-barrel on a Mauser 98 and I would have to say that I've got at least 1600 rounds through it and maybe even 2000. The barrel sees about 50% factory loads and 50% handloads. The handloads are NOT hot ... around 2700 fps. My barrel is given good care, no abuse, proper cleaning. I'd guess this barrel will outlive me.

If I was cranking up the juice on my loads and did not take prudent care of the rifle I might see some issues right now ... but so far it is still my most accurate rifle capable of more accuracy than me.

I don't think it's so much a cartridge as it is the load and the care to the barrel. My .243 will never burn my barrel but slowly wear it down.

Nuff said; applies to all calibers/barrels.

Here's one of the places i've read that it burns barrels:http://www.accurateshooter.com/cartridge-guides/243win/

Yup RR i always take care of my rifles and i think you're right,that's WORST case senario....Thanks for your input.
