I have a Howa 1500 in .308 that I want to get rebarreled. I found a local gunsmith to do the rebarrel, but as we were talking I told him about the ammo I have been shooting. Which is the cheap German surplus DAG 7.62, and he immediately refused to do the rebarrel until I promised to not shoot it through the new barrel. He says that the ammo is bad for the barrel chamber and rifling. I buy it because I am a college student, so I can't afford to shot as much with regular ammo, and can't exactly re-load in my dorm room. Now I know it isn't match ammo or anything, but it can't be that bad when I am getting groups like this out of it at 100 yards.
So my question. Is this DAG ammo really that bad for your rifle? If it is I guess I am going to have to either not rebarrel, or just buy better ammo and shoot less.
