I'm going to build a new hunting rifle in 7mm . I've only owned one in all of my years of shooting. My shots will range from 200yards to around 800 yards I've made these shots before for with other rifles. Just wanting something different. I have a Remington 700 Ultra Mag action I'll be using on this build. The bullet will be 180 or 195 Berger here is some I've been tossing up for awhile. 7mm LRM/ 28nosler/7rum/ 7mm stw. What do you guys think .
