This was my second trip to the range with my Ruger 580 series Mini-14. It is the stainless steel model with the polymer stock. I have a Nikon 2 X 7 X 33 scope mounted in Ruger rings. I started out at 50 yards and was testing various ammo I had at home. The rifle rest was a rolled up soft gun case on a shooting table. The Ruger has not been modified in any way. My first three shots with Winchester 5.56 X 45 55grain ammo clover leafed on the bullseye............... A grin the size of Texas crossed my face. A couple more shots were about an inch below the first three. I then tried Silver Bear .223 62 grain HP and Brown Bear .223 62 grain soft points. They both shot about 1 1/2 inch group at 50 yards. I then tried Privi Partisan .223 69 grain HP and it would not group at all. I then moved out to 100 yards and was getting 3 MOA groups with the Winchester 5.56 X 45, Silver Bear HP and Brown Bear SP. I also fired a few Radway Green SS 109 5.56 X 45. Even though I was switching back and forth between steel case ammo and brass case ammo I did not have one failure to feed ,fire or extract (about 120 rounds fired). I also did not notice any stringing due to a hot barrel. I feel the ammo used and moderately heavy trigger pull limited my accuracy. A trigger job and better ammo would probably put this Mini in the 1 - 2 MOA range. This is a keeper..........Thanks...........
