what is the point of a bull barrel on a .22lr,.17hmr, or .22wmr. i have a .17hmr with a bull barrel and have shot about 100 rounds non stop trying to true my scope. after all those rounds my barrel was only warm and felt nice to the touch because it was cold out.between 50 and 100 rounds i like to clean my gun because the accuracy get a little off. by the time im done cleaning the barrel is cold. i was just wanted to know if the bull barrel was a selling point, something bigger "cooler" calibers need so why not put it on a rimfire to make it seem "cooler" i guess you could say? or is there real accuracy gain in having that larger barrel.
