I purchased a Hastings Wadlock 34 in barrel and it came with three chokes and I would like to purchase a few more. It came with F, Mod, and IM which is ok but I think I would like to have a IC for the 16 yd line. One thing about it, the IM will flat vaporize them from the 16 so you won't have any doubt about how good hits are. I even shot a round of skeet with it and it sure makes some dust. LOL Jackie B.
