Re: Is a .920 OD muzzle on a barrel
If the .920 is the OD of the entire barrel (a straight cylinder such as on a Ruger 10/22) it is a bull barrel. Varmint contoured barrels have some taper to them, a bull barrel is usually reffering to a straight cylinder. But! It really depends on who you're talking to, some will call a varmint contour a bull barrel, so call it what you want.
