I have been collecting brass for several years and have accumulated a good amount of several magnum cases. Most are 300 Win, 7mm Rem, 270 WSM, 300 Rem Ultra and 7mm Rem Ultra. I have been invited to go on an Elk hunt next year and considering purchasing a magnum rifle for this trip (I have a 270 and a 30-06, but thought I might want something with a little more kick for this once in a lifetime trip). I do intend to reload for whichever gun I get so I am hoping to get some idea as to which of these cases last the longest. I have heard that you can only reload the belted magnums 2 or 3 times. Is this true also for the Ultra's without the belts? Right now I'm leaning towards the 300 Winchester as I already have a couple of hundred pieces of this brass on hand. However, if I can reload the Ultra's more than 2 or 3 times it may be wiser to go with one of these. Your suggestions and recommendations appreciated. Thanks!
