montveil, Some of the others here on this forum have found smiths to drill and tap their 12 ga. NEFs but my smith would only do a 20 ga. We had already decided to buy the 20 ga. Trackers and our smith checked one out in the store and decided that .250 the thickness of the chamber area on the 20 ga. was enough. He then proceeded and we couldn't be happier with the results.
froghunter, We had to buy the Trackers with pallet wood stock sets but we both preferred the composite so we horse traded and bought some of the composite stocks we have on both our Toppers and Handi's as well as the Trackers. Congrats to your wife on her deer.
