Hi,
I just ordered a Speed Dial for my Nikon Monarch X 2.5 x 10 x 44 Scope.
I'm mounting it on an X-Bolt 7MM WSM. I'll shoot Win. Supreme 160 Gr. Accubond.
My question is how reliable are the Factory MV's on winchester short mags?
This round has a published MV of 3050 fps. Since I got a 23" tube, my ballistics program put my MV at 3020 fps and that's what I used on the order form.
Just wondering if there is some "Blue Sky" in the factory published MV's. and if I screwed up by not running the stuff through a chrony?
Thanks,
Dee
