Re: Considering my next Mcgowen for my 300 win mag tactical build. Have ?'s
TO be honest I dont know I have heard for every inch you lose 100 fps to a point plus or minus.
I like the look of a long barrel as well and 28" for a win mag or a rum chambering does not seam to be uncomon on here. I think 26" is the norm for a 300 win mag in a factory rifle.
I have one rifle on the way in 260 rem thats not for hunting but I wanted to be able to fire the rifle prone, standing and kneeling as well as over barriers. I went .875 at the muzzle on that for versitilty.
