Another option and an option that Bass Pro will probably lay on you - how sending back to the manufacturer. Or better yet, call them contact them and ask them what to do. I see Cayugad suggest these guns often so in my mind somebody is having good luck with them. I would really suggest making that contact with the company explaining all of the problems you have had. Quality control does not always catch everything - sometimes there are just bad barrels.
And
congrats on the hunt - experiance will make things bigger and better... at least you got to do it - some of us have to work all the time
