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?
Bang...hold up, ok, there it is!
