i currently own a remington 700 BDL 7mm rem mag. Very nice gun actually. I also own a Browning A-Bolt 300. wsm that is a great carry around big game rifle out to 600 yards. The reason i say this is because i cant really put any custom work towards a browning and i dont know how much further it will stay accurate enough to hit the vitals every time. I would like to eventually transition the 7mm into a long range hunting rig. Basically i would like to know my options. If i stuck with a 7mm i would either shoot the 168 grain bergers or change the barrel and have it throated for 180 grain bergers. Now with this action, what other calibers would i be able to turn it into? would like to be able to take Moose and elk at long range.
