I love my S&W AR15-22. Great to shoot as much as I want for about 7 cents a shot. Am looking for a larger caliber as well, or maybe Ruger Precision Rifile or Remington 700 so that I can make 1,000 yard shots.
This is my humble opinion-
Check out the Mossberg MVP. In either 5.56 or 7.62.
The long range versions/target model are tack drivers and shoot well past the scope.
I have shot the 700, Savage 111, Ruger Gunsite. The feel of the MVP and the use of ar-15/10 type magazines, threaded barrel put it over the top.
All IMHO.
