Hello, after dissassembling it, i fired 5 shots, i found 4 , the 5th one is still a mystery...the first one went were i hit, the second one, im not sure were it hit, the first hole was slightly larger than the rest so we figured that it almost hit the same hole, the third hit right were i was aiming and the last 2 were about 1 inch lower from were i was aiming but i think this was due to flinching, this seems pretty good to me, i didn't take it apart this time, but i did run a bore mop down it once to get rid of the debris left by the slugs...
