Thought I'd be clever and clean two barrel(guns) that were absolutely perfect, really didn't take much about 6 or 10 patches each, nice and clean. went out to test them....OH damn, the Maverick .25 was off a mile at 25 yards, ok maybe I rotated the barrel 180º, I put it on slug where I thought it was, elevation was off over a full turn MOA, got it back close and almost ok, still not as close as before I did something STUPID. Next up, the .22 Maverick Compact, off a little bit and went from laser to throwing rocks. I'm hoping that I can foul up the barrels enough to get them back , a few thousand pellets should do the job. After about 70 pellets/slugs each things started to get a tad better but not the Minute of Squirrel at 100 yards they were at. Note to self....IF IT AIN'T BROKE....DON'T FIX IT.
