R1 - .308 Wood? in R1 Rifle Posted April 27, 2014 Interesting decision....I always felt that short action was more reliable in a semi-auto. Hence the choice to go .308. It's been, for a semi-auto, a good gun. No failures, reasonable accuracy and very sharp looking. I have managed to get sub moa at 100 yds with Winchester Fail Ssafe's in 150 gr. Unfortunately that ammo is no longer available. I do have enough to keep me going though, then it will be back to the drawing board as my results with other ammo I tested was much like a lot of others, in the 2-3" range. But in the last ten years new stuff has come out, and I am hopeful to stay within 2". That is sufficient for the northeast. Thanks for the info.
