My guess would be they probably burn the throat out on a barrel rather rapidly.Small bore,large case with a bunch of slow burning powder will do it.Another cartridge,the 6.5/300 Weatherby Magnum,I wonder if you can get a 1000 rounds through it.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
