[QUOTE="Long Time Long Ranger, post: 337518, member: 505"] Rockymtnmt, I understand, maybe the answer is it is hard to wear out a big 338 and there is not much data on it. Some of the 1000 yard match shooters here would be the ones to answer this with a better number since they put plenty of shots down range and know when there groups begin to spread a little. I am a hunter and when I get my load right and zeroed the rifle doesn't get much work. I have well over a hundred rifles to shoot and that limits it also. This is long range hunting site so I guess most guys spend the money for a top long range rig, get everything worked out with it, and then it doesn't get much work except to check zero and hunting. That would be wise since most are on the top end of performance which is directly associated with limited barrel life. For instance Kirby on here has all the Allen magnums which are some of the best long range hunting rigs around. But I would work up my load, zero and use it for only hunting after that. It would last a guy many years then. If he shot it regularly at the range the hunting life would be shortened with it. Bottom line is I have worked with about everything out there which is commonly talked about on this forum except the chey-tac and 50 BMG stuff. I have owned and seen a number of big 30's shot out. During the late 90's I built near a hundred 338-300 ultramags and still get emails from many of those guys. I do not know of a one of them that has been shot out. I have shot the big 338's since the 70's and have not shot one out. My first 340 wby built in the mid 70's has well over 2500 rounds through it and still shoots a 250 sierra game king at 3050 fps very accurately. I have personal 338-300 ultramags, 338 lapuas and 338-378 wby's with over 1500 rounds through them that have still have good throats and shoot just as good as they did when I built them years ago.

The 7mm barrel was gone in 750 rounds like the 30-378. I still have at least two of all the other calibers and all are still shooting great. From all of this I would gather that once you get to 338 caliber and above barrel life goes up considerably. Big 7mm's and smaller don't last very long, and some huge 30's are about as bad. [/QUOTE]
