I have been reloading for a number of years now. I am undertaking the 7 mm Mag now. It is really for my Friend who hunts with that round. I have always used Lee Dies and been very happy with them. I have a new problem though. I just got the die in. The picture of the OAL with the die set instructions shows the casing substantially shorter than my Friend's once fired factory Remington Brass. What is the deal with that? I know repeated firing slightly lenghthens the brass necessitating trimming. However it could not change this much from one firing. Am I missing something here? When reloading , anything that looks different or makes no sense to me causes me concern. Did anyone else notice this discrepancy in length?
