Ok I have Remington 700 lss in 7mm RUM.. After two surgeries on my shoulder I can't shoot it unless I put a break on it.. My question is since I won't be using it for awhile I want to rebuild it. What are your guys opinion on a caliber I loved my 7RUM but I herd of this 7RUM XL??? I don't know much about it? Yes and the Gunwerks 7mm LRM which I don't understand why it has better BC then both the STW and RUM?? That another question for you guys? I think I want to stay with a big 7 because I have 300rum.. So what is a good big 7 for long range hunting or even your favorite big 7???
