I have been checked twice in 16 years. The first time I had a brand new gun that I patterned and did not even check that it did not have a plug in it. I was hunting illegally. I told the GW that the gun was only 3 days old and I just shot it one day and never tried to put more then 3 shells in it at a time. He let me go and I went home and got a plug out of another gun until I was able to get one from the store.
