I read and reread you'alls advice on the other thread. I am still thinking about it all. What are the advantages of the 300 Rum over the 338 Rum and vice versa? Right off the bat, 30 cal bullets are endless and I already have several other 30 cal rifles. Just buy lots and lots of 30's and forget the 338s. That seems like an advantage for the 300 rum over the 338 Please comment, I am new and I have to read stuff twice and get explanations twice What is an 30/338?
