Its not my theory. Or that matter its not a theory, this information has been posted in several books buy some of the most respected gun authorities in the last century. This didn't come from the local self trained gunsmith down the road.
All thing being equal....a thin diameter barrel shoots just as accurate as a thick diameter barrel. Forget all the various crap use in a 20lbs bench gun we are talking about the same barrel length just different diameters.
Meh,....I am not trying to impress you. Shot off sandbags on a windy day. Your welcome to post some of your own targets if you like and let's see what you can do with a light weight rifle and off the shelf ammo.

Two different days. Two different off the shelf ammo on less than ideal windy days. Using a 9x scope.

Wanna bet I can't get my groups under 1" on a calm day with better optics...?
