So who here has a 7mm mag? What ammo have you used with good success? I have tried Federal 150gr sp thus far but also have prvi partzan 140 btsp and 174 gr btsp's. I haven't had a chance to shoot the last two yet, but think that they will be decent based on what I have read. I am looking for a good match ammo that has a good BC so that if I so choose, I can shoot out to some longer ranges (probably 500 yards for now as I don't have much more room where I currently shoot). So basically, who's got em and what do you use? Thanks!
