In 40 years of western big game hunting and multiple hunts on 3 continents, I have only had one gun failure. When hunting a Caracal in South Africa, the primer failed to ignite the full case of powder, but had enough force to lodge the bullet in the barrel. Luckily, my PH had a borrowed .22 LR rifle in his truck, and I used it to shoot the Caracal. We couldn't get the stuck bullet out until the next day. The other 19 cartridges in that box all fired flawlessly. I now carry an 8" piece of brass rod in my rifle case, that can be dropped down the barrel to dislodge a stuck bullet.
