My 16 ga. 28" NID weighs more than that, about 6 lbs. 11 oz. as I recall, so I'd re-check your scale calibration using some known exact weight closer to 7 or 8 lbs. I've never seen a 4.4 lb. bag of sugar. I thought most brands are now 4 lbs. even. My old spring scale would give quite a variance depending on how well centered the gun was on the platform.

Voting for anti-gun Democrats is dumber than giving treats to a dog that shits on a Persian Rug
