Ok..I just got back from the gun range, and this is my findings. I am not the most knowledgeable person when it comes to terms, mechanics, and lingo of a gun. So bare with me. To each is his own on their results. Not every gun shoots or reacts the same.
When I first bought the gun, I took it to the gun range. Horrible results! Cleaned it up during and after really good. Puppy was dirty. Next time I took my son, so he can get the feel for the gun. I used the same ammo(federal power-shok) and came up with the same results-ALL OVER THE PLACE! Ok. Not the first time a gun has reacted like this. So I went and bought a box of remington core-lokt and winchester super-x. And after reading everyones comments, I thought it was hopeless.
Before I headed to the range today. I checked everything to make sure all was tight. It was. Then I got the idea of comparing the radius clearance between the exit radius of the bore and the radius of the bullet(stuck the bullet into the end of barrel and wiggled it). I found out that the remington and the federal was very tight either top & bottom OR right & left. There was a lil play on which ever direction wasnt tight..duh!! With the winchesters, there was clearance all the way around. All 3 brands were 100grain. HMMM, interesting.
Got to the range and started with winchester..was way off. Only fired 2 rounds at first though, before switching to remington. I heard people has had luck with it. Well initially it started closer to target, but was very unstable. Like the federals...ALL OVER THE PLACE. Shot half a box, then gave it up and went back to the winchesters. After a few shots, it was starting to look promising. And it was. The shots wasnt all over the place. YAY!! Maybe I can work with this then. When I finished, I was grouping about 1/2-1 inch off from target at 100 yards.
So if you or someone you know is having accuracy issues with this gun. I hope this can help. But again, not all guns are exactly or shoot the same.
