I need to get my barrel ordered for my 7 mag build. I am thinking of going with a Mcgowen in a #5 fluted contour 26". Anyone put a #5 in a H-S precision Remington 700 LA sporter stock. Just want to make sure it will work without having to remove too much of the barrel channel. Mcgowen makes several #5s to match other barrel manufacturers contours. Any recommendation which will work best? I think a fluted #5 would be a little better than a #4 for both stiffness and aesthetics. A #4 would however be cheaper as I wouldn't need to flute. I'm trying to keep my barrel under 4lbs. I'm thinking the factory 24" mag barrel is about 3lbs and want about another pound of barrel weight. Thanks.
