[QUOTE="J E Custom, post: 1741432, member: 2736"] Barrel life depends on many things and most of what we (Long Range Shooters) do shortens barrel life. The hotter we allow our barrels get the faster they will erode. the faster the projectile goes the more it will erode. the more powder we use, the more the barrel will erode. The higher the pressure, the more erosion will take place.the more carbon left in the barrel, becomes an abrasive, the more erosion, the dirtier we allow our barrels to get, the more erosion will take place. These are just some of the causes of barrel erosion. To answer the OP's question, If a 338 RUM is pushed to the limits, it will normally have less barrel life than the 338 Edge loaded normally. If both cartridges are loaded to the max then the 338 Edge will not last as long. So barrel life is greatly effected by the owner and his care and loading practices. Below is a good metallurgical description/explanation of the causes of barrel erosion. It is a bit of an in depth description and may be difficult to understand if you have no metallurgical background, but if you read through it several times it will all make sense.
