Advertised weights are probably rounded, not necessarily precise. If all H&R bull barrels have the same outside measurement and contours, there's no way a .45-70 and a .223 could weigh the same and I don't believe H&R makes all rifles weight the same by changing the stock weight to make them weight the same 7lbs. Some are going to weight 6.5lbs and some are going to weight 7.5lbs, so they pick 7lbs as an average. I'll be weighing some of mine today with a digital fish scale, forgot I had it! :oops:
