kay I just picked up a Winchester Model 70 Sporter Magnum 300win mag. On the side of the barrel it says "Winchester Model 70 Sporter Magnum 300 win mag" ... The problem is I can't find any information on a Sporter Magnum Model 70. Are these the same as a regular model 70 Sporter? Does anyone know the value of one of these? I would love to know more about it. Thanks.
