Took part in sporting rifle competition on Sunday, 100 and 200m, 40 shots at a variety of animal targets, all shots sitting with sticks. I was unable to shoot at 3 target exposures due to sorting out a failure to fire. The failure to fire followed a pierced primer (see pic). Testament to the AW that, after a bit of bolt jiggling (but not stripping) it continued to fire....despite having a piece of brass inside the bolt assembly (see pic of what came out when I stripped the bolt yesterday evening). Not sure what to put this one down to.....a brittle primer?
