Nathan FosterHI Bill, its funny how weight is a subjective issue. I went to check the weight of my .338 Edge for you. I build this rifle as a "medium" weight. It breaks the general rules of an Edge build and rather than a 30" full contour barrel, it has a basic 26" semi varmint contour onto which my forward port brake is fitted. Steph has been sniping cow pats with it of late, so the partial recoil reduction is quite fine with the forward ports- as long as the rifle is held properly.
As for the weight. The contour is a True-Flite #4. The muzzle (before threads) is .730". The thread is M16. The weight of the rifle ready to roll is 5.2kg or 11.44lb. To me, its a medium weight rifle. The scales say otherwise. My perspective is subjective, not objective.
You could save some weight by having less meat at the beginning of the barrel. Mine is full contour for 3", then slowly tapers.
The brake weighs 150 grams (.3lb). The stock weighs 2.9lb.
A basic 1:10 twist will allow you to use the full range of bullets. No need for anything faster.
