It's about 8.5 lbs. It's the Dakota 97 Long Range Hunter. I have dies for it but I haven't had to load any ammo, yet.
There's some truth in his article, for all practical purposes for average hunting under 300-400 yards an animal won't know the difference between any of them.
The big mags need big long barrels to take advantage of their capacity and then shoot big long heavy bullets. The energy retained past 500 yards with the big bullets just can't be beat. There's no replacement for displacement.
