 | Gunsmith - How a bolt action functions - All 8 steps When cycling a bolt action rifle eight different things happen. In this GunTec presentation Larry Potterfield, CEO and Founder of MidwayUSA, explains all eight things that occur when the action is cycled using a Mauser 98 rifle. First, as the bolt handle is lifted the bolt handle contacts the primary extraction cam located on the top of the rear bridge. This begins the extraction process. Second, the cocking piece moves to the rear cocking the action for the next shot. Third, as the bolt is rotated, the firing pin is blocked as a safety measure. Fourth, as the bolt travels to the rear, the ejector kicks out the empty case. As the bolt is pushed forward the next cartridge is stripped from the magazine and pushed into the chamber, this is number five. Sixth, closing the bolt causes the locking lugs to seat into the lug recesses in the receiver. Seventh, as the bolt is rotated the firing pin is unblocked so the next round can be fired. Last, the cocking piece is blocked by the sear, making the gun ready to be fired with the pull of a trigger. |

 | Gunsmith - Rejoining shotgun barrels Once the barrels on a shotgun become loose on the receiver they need to be rejoined, or set back on face. In this GunTec video Larry Potterfield, CEO and Founder of MidwayUSA, tightens an old Parker Brothers shotgun by rejoining. This process begins by TIG welding the inside of the hook on the barrels, adding just a few thousandths of material. A course round file is then used to file down the excess material, regularly checking the fit of the barrels to the receiver using a smoking process. This process is repeated, both on the hooks and the face of the breach using increasingly finer files until a perfect fit is the result. |
