Bore Size Archived Message Posted by William on July 7, 2008, 4:47 pm I recently purchased a 16ga LC Smith 28" barrel gun in excellent condition. In measuring the bore size should the bore at the muzzel be the same for a mod/full choke gun? I read in the LC Smith Shotgun book that you measure the bore from about 2 1/2 inches into the barrel?
