I recently purchased a rem. 700 BDL SS chambered in a 7mm STW. I believe this perticular gun was made from 1997-2001 only. It's got a factory muzzlebreak. I have been shooting since I was able to shoulder a gun. I have never "broke in" a barrel. i went out, sighted my gun in and then took it hunting. It wasn't untill reading posts on this forum that I even realized there was such a thing. I rarely shoot more than a dozen rounds in one sitting. This STW I found was a heck of a deal. being that it is at least 10 years old it had only been fired 14 times and is still in the box. The guy bought two boxes of ammo when he bought the rifle and I have them now. one is full and one has 6 rounds left. He said it was too much gun for him. The muzzlebreak tames it down pretty well. I have an 8mm rem mag with no break and it kicks much worse! I like the new gun and want to do it right. So what would be a proper "break in" for my barrel? I appreciate some help on this issue as I am obviously a "retard" when it comes to this... I hear they make a 257 and 264 STW as well. What are your feelings on those rounds? Does anyone make a 30 cal on the 8mm case?
