After reading this article about a 7mm WSM (bolt gun) shooting half-MOA at 1000 yards off a bipod I have always wanted to build (or have someone build) an AR in 7mm....and see what kind of groups I could squeeze out of a gas gun. half MOA @ 1000
The shoulder on the 7 wsm cartridge is too steep for reliable feeding according to GAP. Other gunsmiths do them but I am skeptical .....nothing is worse than an AR that won't feed reliably. 7-08 is done a lot so it is a possibility but I wish it held a little more powder. If I remember right the 7 saum cartridge production has been dropped. I will do handloading for ultimate accuracy but want to stay with a cartridge that is also commercialy available and will work in an AR......so it looks like 7mm-08 is about the only choice in 7mm.............am I missing anything. Any other 7mm rounds people have had success with in an AR?? Thanks, Jim |
