2 misfires!! WTF???

[Hitzy]

Colour my silly, but even if there wasn't any powder in the case wouldn't the primer at least still detonate and make a bang instead of a click?

There was NO NOISE at all when I had my 3 misfires and the primer went off with enough force to jam the bullet into the rifling each time. If you had a misfire and quickly ejected the shell and didn't examine it or the bore to see if the bullet was stuck in there, then loaded and fired another round, it would be catestophic.

I'm a bit confused Sunray. If the round fired after it came out of the chamber why wouldn't there be an explosion (not a big one but a contained explosion nonetheless) ? Would there still not be 55 gr. of powder sitting in a case with a small explosive device firing behind it to ignite it? I'm thinking I wouldn't want to be holding it or even standing over it if and when it went off.

Smokeless powder needs to be confined under pressure to detonate with force, hence it's designation as a propellant and not an explosive. Out in the open, it just burns kind of like a sparkler.

Could be your gun :?:

hey, same problem about a month ago, three misfires with CCI's, I went and bought a box of factory loads for hunting to be sure

I would be quite sceptical that a round would cook off when it has already made contact with the ground.

The only time I've heard of a round cooking off when not chambered, was when some of the older ipscers habitually picking the round as soon as it was extracted, i.e. the hand was covering the ejection port (1911) and the round struck the ejector pin and cooked off

There were some pics of a guy who had a misfire go off in his had. Nasty!! Minor perhaps but you don't want it to happen to you!

I think that they were in General Discussion , not off topic. Doses anyone remember?

I never use cci primers for hunting, but they do occasionally go to the range with me.
The only misfires I have ever had were with cci now that I think of it...........

Hang fires are inherent more to black power rifles, with pre primer ignition devises. Primers that generally fail to go bang the first time around are most likely due to dirty mechanisms, primers seated too far inside the primer pocket, contamination of the primer or damage during installation. The few that I have had will result in running it right back into the firearm again with usually no failure on the second attempted. If you don’t have the proper tools to pull them then it is a good idea to have a place to dispose them, or give them to me.

My only misfires were with winchester primers.

Two questions:
(1) How far off the lands were you?
(2) Are you sure there was powder in the case?

I have seen bullets loaded long, with no powder, since the bullet was up against the lands, it never left the case. And was extracted intact.

Pulled the bullet after and found an empty case, and obvious burn marks on the bottom of the bullet from the primer.

From reading your post it is not clear if you pulled the bullets.

Bad practice!!

what was the temperature? could your bolt be gummed up with grease?

also, does any body know the results of a non chambered (ie: not confined) round going off? i heard that it is minor, but don't want to find out.

Among the bad things we have done (KIDS, QUIT READING) is to set a loaded 30-06 cartridge on an airtight heater in a cabin, with a fire in the stove!
Because the brass is against the stove, the bullet flies out and it rattled around the peaked roof of the cabin. Of course, we took precautions to protect ourselves. The brass is unchanged, looking like new, after going off. The bullet hitting the board ceiling wouldn't even make a mark that could be easily seen.
Surprisingly, a 22 long rifle given the same treatment, setting them on a hot stove, makes a far larger noise than the 30-06. Also, the 22 is more dangerous, because the case ruptures and sometimes pieces of it fly around.

Sure you didn't get anything on the primer while seating it?

I allways wash my hands before handling primers!

That what I was thinking. Try to handle th primers as little as possible.

primer

CCI BR2's are for benchrest accuracy, but duplicate std primers. I cant see that making a difference. Only thing can think besides contaminated primer is seated to deep or shallow? Assuming flashhole clear and powder in the case.
Havent had a handload misfire in near 30 years. Try visually inspecting the remaining primers, if good load them using extra, extra care and fire em off at the range and see if problem re-occurs. Certainly wouldnt hunt with that batch though.

Even though this thread is two years old I will give my opinion..........

In order to fire the primer must be set firmly enough into the primer pocket that the anvil is pushed back into the priming compound. If the anvil is not in firm contact with both the bottom of the primer pocket in the case and the compound in the primer a hit from a firing pin will not set of the primer. Often the primer hit will seat the primer which is why these types of misfires will fire if the cartridge is fired a second time.

With ILBR going from Winchester primers to CCI bench-rest primers lack of seating depth could very well be the culprit. The Winchester caps are soft and seat very easily with very little pressure. The CCI BR primers on the other hand are slightly larger in diameter and are "harder" as well. They require a fair bit of pressure to seat properly.
