Misfire

[Grey_Lion]

To be honest with you, I think the primer did not go pop, or whatever it does, so I think I had a bad primer in a case with no powder.

Primer is a Winchester small pistol and it was seated properly.

The typical primer will make a significant amount of sound. Take one out into the driveway some time and throw it down forcefully on the pavement. I had a deformed primer once and did this to "dispose" of it. It's almost as loud as the firing of a chambered round.

In a solid load process, the odds of having a bad primer go into one case which got no powder is incredibly slim..... - give up the lotto, you've blown your luck on this one event.

Happy this event ended without mishap.

I initially used Winchester primers but switched to CCI after the first 1100 WIN. I've had better luck and performance from CCI 500's in pistol.

I had a lot of squibs in my 454 Casull.

Loading 38.2 grains of H110 using small rifle primers... would not light all of the powder.
Switched to a small rifle magnum primer and not one squib since then

Ok, as this is not a squib but a primer only ..........

If it was primer, it contained in a heavy gun, surrounded by a sound deadener and contained in the bullet.

It not open air or a no bullet in the case.

I am assuming but with ear muffs on?

Its a larger case than a 9mm which goes only a bit into the barrel.

Now I am going to have to build a non powdered 44 special and see what it does in a revolver. I will let you know.

A shooter brought 5 failed to fire 30/06 rounds over to be checked for fail to fire. I pulled the bullets and powder and then I removed the primers. I installed the primers back into the came cases they were removed from and then reinstalled the primers.

I dug out one of my M1917 rifles and then chambered the cases one at a time and pulled the trigger. It was noisy.

I measured the length of the case from the shoulder to the case head before I started and I measured the length of the cases after I busted the primers. I thought about calling the Aberdeen Armory because workers there claim the firing pin striking the primer shortens the case from the shoulder to the case head .005".

And then there is the "Rest of the story". The rest of the story goes something like the shooter purchased a new 30/06 Ruger rifle with two boxes of new R-P ammo. 5 pf the first 120 failed to fire. He then passed the 5 failed to fire rounds to 4 shooters with 30/06 rifle in an attempt to determine if another firing pin would bust the primers in the failed to fire cases. All of the shooters took at least 2 attempts. So I figured there were at least 10 attempts at busting the primers.

NOW! there were rounds that no attempt was made at firing the new rounds. I measured the length of the failed to fire rounds, I measured the length of the l cases that fired from the shoulder to the case head and I measured the length of the case from the shoulder of the case to the case head on the cases I chambered and busted.

I used fail proof home made gages when measuring the length of the cases from the shoulders to the case head. Was I surprised? No; even thought the firing pins in my M1917 are killer firing pins I have never agreed with that silly story about the firing pins driving the case forward and smacking the case into the shoulder of the chamber hard enough to shorten the case.

I did ask if they would consider other possibilities.

Yes , in a J frame S&W , 38 special , a primer ignited and drove the jacketed bullet half way into the forcing cone , the Good Lord left the other half of the bullet protruding into the cylinder,
the young fool , who did the reloads , tried to cock the pistol again but it was locked up tight....thank You Dear Lord for saving my ignorant self.

A soft lead bullet, in a 38 special , the primer will be drive the bullet past the forcing cone into the barrel , the cylinder will turn and the gun can be fired again ! That situation will get you into trouble....but I learned... no bang , no recoil, no hole in target , anything out of the ordinary.....STOP !
You might have a problem !

I also learned it's OK to get real anal about powder charging .. I inspect each case for powder at least twice now...maybe three times .

it won't in a 6 Creedmoor. I had a no powder load today, primer went off. It did not look like the bullet even moved. Primer was backed out of the case by a good .1 inch so I could not get a good measurement on OAL

The bullet did not move but the primer did It should have moved no more than .005" if the clearance was perfect. The distance from the shoulder of the case to the case head should have measured 'minimum length/full length sized' and the chamber should have been go gage length.

When checking the length of the chamber from the shoulder/datum to the bolt face it was recommended reloaders seat a spent primer partially into the primer pocket. How much protrusion? .010" should be enough protrusion because it is unusual to find a chamber that is go-gage length + .005".

Again: I have a rifle that has a 30/06 chamber that is go-gage length + .016". this is not a problem for me because I add .014" to the length of the case between the shoulder of the case and case head. The .014" give me the magic .002" clearance; all of this is possible because my cases do not have head space.

The primer protrusion of .100" could have been a wild guess. And there is remote chance the bullet was seated into the lands and the shoulder of the case was setting against shoulder of the chamber and it could get complicated if anyone wonders how the firing pin got to the primer if the case head had .100" clearance.
