[QUOTE="Long Time Long Ranger, post: 456690, member: 505"] I had a bad problem with extreme throat erosion with the 7mm RUM. I think the 7mm STW is about the best you can do in 7mm before reaching an extreme barrel burner. I got excellent velocity and accuracy out of the 7mm RUM, just no longevity. I don't have my notes with me but I think on average it was right at 120 fps faster than the STW with 175 grain bullets. 120 fps was not that important to me compared to replacing barrels often.
