Every time I see TACTICAL RIFLES, they are in .308 or .300MAG and .338 Lapoua. I have a 7MAG I got from a friend back in 1982 its got a heavy Barrel and sets in a HS Precision Bench rest stock with a Burris Scope..My plans are to replace the Barrel back to the 7MAG. I just love what it did when the Barrel was new it needs to be changed(shot well over 5000 rounds)why do they not recognise this calibre? anything at 500 yards is dead(Deer) even woodchucks. I like this better than the .308?
