Old Mossy Horns
I settled on Leupold STD base and rings. Never had issues with this set up on other rifles and I trust it's dependability. Mounted a Burris Fullfield E1 3x9-40 w/30 mm tube on it. First 2 shots less than 1/2" apart. That was the end of the nice group. Made adjustments, where did they go? Well, I moved it back, tracking must be off s little. Try again. Made adjustments, Trying to bring POI down, but group did not move. Shot another group after making adjustments again. Hit same height. But for the most part same left and right. All right from finally a decent group. Let the gun cool off. First shoot 6" low. Next shot 1" high. Next shot 4" high. Let the gun cool. Same thing. Then s as me thing another time. Rapid fired got gun hot an group good again, dead on. Cool 6" low. Same old same old. By this time my wallet and shoulder had taken a beating. I'm also satisfied the gun is stringing the slugs vertically higher and higher as barrel heats, very minimum heat. I'm feeding up at this point. I'm frustrated but not as disappointed as my girlfriend who bought the gun for me. I shot Remington acutips and Win. Dual Bond slugs with identical results. Well, I thought the forearm has to be putting pressure on the barrel somewhere or the recoil lug screw is loose. Well, I got home and sure enough the recoil lug screw was less than snug. I'm thinking this could have been my issue. I will try again. Any thoughts? On checking on other variables.
