What kills barrel life on bigger magnums?

What causes the loss of barrel life? Obviously the more the velocity the less barrel life. But lets say the barrel is well cleaned and taken care of, Is it the amount of powder being pushed down the bore?

    Using the trigger as a giggle switch repeatedly! A couple shots then checking conditions and letting things chill will go a long ways!

    Excessive heat and overbore calibers is what kills barrels. It's the nature of the beast and a vicious cycle.

    Bigngreen, thanks for your reply.

    Not quite what I was asking, but I still appreciate it!

    Here's my dilemma, I have like a day or two to figure this out. I just ordered a LRKM from Shawn. I'm stuck between the edge +p and the terminator +p. the main thing pushing me away from the terminator is loss in barrel life. But here's where I'm confused. In a 30" barrel, Shawn is getting about 3040 fps with 101 gr of n570, Broz in his terminator is getting 3210 fps with 111 gr of n570 (out of a 32" barrel) So obviously the terminator will lose barrel life faster. But what is causing it? The 10 grns more powder? The extra 170 fps?

    This is so freakin hard to decide on which case to use!!

    Both will be a factor in barrel life, more powder, more speed, more heat, all through the same size hole.

    Get the 338 Terminator +p & don't look back

    How you shoot each will make the big difference, where the powder burns makes a difference, the Lapua case being larger may let more powder burn in case, I honestly think at this case capacity you won't see much of a difference between the two. I've shot Jeff's a few times, between the performance and the Lapua brass when I order mine it will be the Terminator without a doubt!
