Hi people, i have this question right.. uhm, we at my club are told to hold the firearm pointed in the forward direction down range toward the end of the range at all times in case of a misfire for 20 secs in case of delayed discharge..logically, so now., i shoot .22 cci standard right.. my question is this.. is it likely and possibly that .22 ammo can dischcharge after being striked by the pen a giving time after the striking or is this only the case with primers from larger calibers? love to hear your expert analysis. grtz Dutch.

It is called a "Hang-Fire", and it is just as likely with a rimfire as a centerfire. Just because the primers are mechanically different, they are the same chemically.
Hang-fires have been known to occur up to a minute after the primer was struck, although the likelihood of this happening is only one in several hundred million. The usual hang-fire is only long enough to be aware it happened, a small fraction of a second. The usual advice is to keep the gun pointed down range and to not open the action for 10 seconds. If the rules on your range require 20 seconds they follow the rule, even though it may seem to be a bit of excessive caution. This is for your safety as well as others.

I have never experienced a .22 rimfire hangfire in tens of thousands of rounds fired. Many misfires for various reasons, but never a hangfire.
It's possible to "create" a hangfire with the wrong primer and powder combination. I managed to do this with starting loads of BLC2 powder and standard primers in the .30-06. The delay was only about a quarter second but it's very obvious when it happens.
In all my years of competitive revolver shooting I have NEVER seen anybody wait 10 seconds or even one second when the revolver didn't fire when expected. Given all the high primer handloads and undersprung revolvers at the matches, the "dud" round is a very common occurrence and nobody gives it any special treatment. The shooter either goes on to the next cartridge or the offending cartridge is ejected on to the ground. I have never seen an ejected cartridge hangfire.

Thank you for your reply, i will keep in mind that there is a small change that a hang fire can occur with .22 rimfire cartridges just as with centerfire cartridges.
As far as the waiting period is concerned when it happends, the official Dutch safety regulations advices a 60 secs waiting time..talk about excessive caution..but we can never be safe enough right!
