Description
The BoreMaster measures all the inside dimensions of your shotgun:
- BORE — .410 through 4 gauge and rifle barrels .405 and larger accurately in thousands
- CHOKE — fixed or screw-in. Measures screw-in chokes in or out of the gun
- CHAMBER — Chamber dimensions — Chamber length — Forcing cone dimensions and rifle chambers with diameter dimensions of .400″ and up.
WITH THE BORE MASTER, YOU CAN ANSWER THESE QUESTIONS:
- Have the chokes on a gun been altered from the barrel markings?
- Are the barrels overbored? Original or aftermarket?
- Are the chambers 2″ or 2-1/2 “? Have they been altered to 2-3/4″ or 3”? Reproofed?
- Is the barrel wall thickness safe (6″ from the muzzle or breech)?
