[QUOTE="Broz, post: 598781, member: 7503"] My experience with the 7stw is much different than yours. And the ones I have been around had great care taken about heat and never more than a 3 shot grp. So I was up at Dave Youngs yesterday (Youngs Custom Gunsmithing) dropping off another 7mm-300 build I am doing. Dave has done everything with the 7 stw that one could do. This includes one of his favorite rounds the 257 STW. Dave likes high velocity rounds and builds a ton of them. Dave has taken special interest in the 7mm-300 wins I have had him chamber for me. But that another story. So I asked Dave, under normal conditions with no abuse, when do you start to see throat errosion of the 7mmSTW. He quickly rplied at 500 rounds. Then went on to say by 1000 rounds most of them are ready for a new barrel if the shooter wants to retain their capable accuracy. Now that does not mean they will not still hit a gong at 1000 if they have 1200 rounds through them. But for sure theyare dying a pretty rapid death after 500 rounds by my standards. For what its worth, and this has also been my experience and why I say the 7mm -300 win is as large of case as I want 7mm for as much as we shoot.
