[QUOTE="goodgrouper, post: 62950, member: 2852"] The 7mm Ultra is probably the worst barrel burner for a factory chambering going today. I lost competitive accuracy on my .300 win mag after about 1100 rounds. The 7 Ultra shoots about 20 grains more powder down a smaller caliber hole, so you can expect about 30-40% less barrel life than the 300 win mag. Keep it very cool, clean it often, and don't be too experimental with load development. Shoot it when you have to, and don't use it for prairie dogs and you can get several good hunting seasons out of it! [/QUOTE]
