Yeah, did that about ten years ago buddy and as it happens last week also so don't worry.You should pattern any shotgun , not so much to see if there donut holes in the pattern ( when the barrel is moving that will all be different ) but where the gun is patterning , above point of aim , left, right, below , I like my trade gun to pattern 55% above and 45% below the point of aim at 25 yards , there is not much point shooting rabbits if you dont know where the load you are using shoots on at whatever distance you shoot rabbits at.
