I like to shoot a lot and having something featherweight defeats my desire to do so. More than three to five shots and the barrel heats up so much the rounds start moving away from the original zero. Not to mention less mass equals greater felt recoil which will cause the shooter to produce an unconscious flinch...the later goes for everyone whether the want to admit it or not. Point being, it seems hard to me to imagine truly enjoying and becoming as proficient with a 5.5lb large caliber as one would with a heavier one.I really like the 7 mm, but would need to find a really light weight one like a Sako Finlight! My Mauser is 9 pounds, and that gets to be a bit much to lug all over the mountains! Maybe i'm just getting to be a puzzy in my old age! LOL
