Back in 2004 I was sheep hunting with my Dad and brother and we fond a band of abut 12 rams. My dad had "first shot" because he was "old" and I won the toss for second shot. When w finally got I. range of the band (after 2 days of stalking), Dad shot his ram and, of course the band lit out at full run. I ran after them for a couple hundred yards until they went into a small ravine out of sight and when they started pop up on the other side (maybe 100 yards distant) I watched through the scope (prone) waiting for the one I had picked out previous. When "my: ram came out of the ravine it turned broadside and stopped. I put the cross hairs behind the shoulder and squeezed. CLICK!. WTF. I did not know if I had forgot to load the thing or what happened but did NOT want to open the action in case of a hang fire. I was hooting a Ruler No1 and was laying on my ammo pouch. I moved the breech away from me and open the action and out popped a cartridge, I rolled over to retrieve a fresh one and reloaded. By this time the rams were all on the run again. In the end, I did get the ram I wanted just had to shoot a bit further and my brother got his after chasing them for over a mile. Anyways, the "dud" DID have powder in it, the primer just failed to fire. That was the ONLY time in my life that I had a centre fire cartridge fail to go off (and of course at the most inopportune time) but I was quite nervous opening that action even though I had the breech pointing past me not AT me.
