A Cylinder bore has no choke at all.
If there was no damage to the cylinder bore then you will not need to bore it oversize.If there was no damage to the cylinder bore then you will not need to bore it oversize.
The bore of a cylinder describes is measurement, in millimeters or inches, of the inside diameter of the cylinder. The diameter is the width across.
Yes. An inside micrometer or bore micrometer can be used for measuring the bore of a machined cylinder.
I have an Australian delivered 94 Model and it has a nikasil (sp) plated bore.
This is the diameter of the cylinder hole in the engine block for the pistons.
"Cylinder bore" means the bore diameter at the muzzle is the same size as the bore at the front of the cylinder where the shell is when it's fired. Shotguns use "choke" settings to restrict the size of the mass of lead pellets coming out of the muzzle to tighten the mass down onto a further target....a cylinder bore gun has zero choke restriction so the mass of lead pellets stays wide and spread out. Cylinder bore guns are meant strictly for close in targets for that reason.

Bore is the diameter of the piston/cylinder, stroke is the distance the piston can travel between its highest position and its lowest position in the cylinder.
