BobinNH,I surely hope that my wife doesn't read this post. I also hope that she doesn't realize that her 8# 12 oz.(scoped,loaded,and with sling) .338 WM,which she uses for deer,antelope,elk,bear,moose, and God willing a possible Alaskan and/or African hunt isn't really a practical all around,all purpose hunting rifle! Maybe with a rifle that heavy,
it explains why she refuses to use a muzzle brake. Anyway,all things being equal it seems that a rifle with a "bigger" hole in the barrel,should weigh less than one with a smaller hole
