How many rounds can I fire of 7mm Magnum before my stainless steel barrel wears out, to the point of declining accuracy? The loads would be 160 gr. class at 3000 fps+, with 65-73 grs. powder. Would switching to a heavier bullet, like a 175 gr., when erosion makes shooting 160 gr. unfeasible, be best at some point?

MMAM, You should be able to get 1000rounds or so if your lucky, before accuracy drops off, after 2000 rounds you'll drop about 200fps, a heavier bullet isn't going to make that much difference, if shooting Longrange try the 162 A-MAX or 168MK, probably the main thing is to not overheat the barrel. **** the torpedoes...full speed ahead!
