over the Marlin 795:
In an Appleseed shoot this weekend we had two different Marlin 795s suffer OOBs (out-of-battery discharges), one of which resulted in a bullet lodged in the barrel. Fortunately nobody was hurt, and there was no permanent damage to either rifle.
In each case, the cause was a dirty chamber that prevented the round from seating fully. Even though the bolt was not fully in battery, the hammer hit the firing pin and ignited the round.
This can happen in the Marlin 95 because the firing pin is in the bottom of the bolt.
But it can’t happen with a 10/22, which has its firing pin in the top of the bolt. In the 10/22, if the bolt isn’t fully in battery, the hammer will be blocked by the lower rear edge of the bolt and will not be able to drive the firing pin into the cartridge rim.
Many 10/22 owners complain of light primer strikes and failures to fire. We know that the cause in the vast majority of cases is owner negligence – failing to keep the chamber clean. But at least these malfunctions don’t risk blowing up the rifle. Just another example of why Ruger’s design of the 10/22 is so great.
