I've been playing with a Remington 5r Milspec 24" for a couple of months now. My accuracy has been about 2 MOA with cheap .308 ammo until this weekend. After reading numerous posts stating that the 5r requires 168-175 gr match ammo to attain sub MOA groups I finally purchased some decent .308 from the LGS. I ran a box of Hornady 168 gr BTHP Match through the weapon on Sunday. It made all the difference. The firearm was finally as accurate as I could hold it. I shot a 5 shot group I could cover with a quarter at 100 yards. Thanks to all the seasoned shooters showing me the way. I will try other match ammo in the future (Federal Matchking in 168 and 175, etc.) and anticipate eventually getting into reloading.
