Re: 7 wsm ballistics
I have a SakoAV that was chambered in 7 Rem Mag the best load I ever worked up for it shot 160 AB's at 3025fps. Last year I had Fiftydriver put me on a new barrel chambered in 7-270WSM so I could use Norma brass (1 or 2 grains smaller powder capacity than a standard 7WSM) it shoots the same 160 AB at 3185fps. the chamber on this rifle does have a longer than normal throat so I dont think you could get this much velocity from a standard chamber but close.
p.s. I have been spending way too much time in your neck of the woods lately, both of my children live in Mesa. my daughter graduated ASU 2 weeks ago.
It takes 43 muscle's to frown and 17 to smile, but only 3 for proper trigger pull.
