I have just recieved approval from the house appropriations comittee (spouse) to buy a new barrel. I have decided that it will be either a 7mm rem mag or a 300 win mag, with Leupold qr base and rings. I have not shot a 300 or 7mm but would assume that recoil will be somewhat less with the 7mm. I don't plan to hunt buff or bear with it, mostly deer and pig. I have a 7x57 so bullets can be used for each. Any thoughts?
