Fail to fire................
 
We've all had the same problem with 22 ammo. It's my understanding that the powder that sets things in motion is in the rim of the casing. So to make it fail to fire the powder is not 360 degrees, Could this be that when you buy in bulk the rounds are laying flat or at angles and get jostled around causing the powder to settle in one area. similar to panning for gold. We all know that some times more often than not turning the round away from the firing pin mark will result in the firing of the round. Are those people with less fTf buying ammo that sets upright in containers............I needs to know..........

I always thought they were bad primers:confused:

Now you've got me curious.

Remember, this is not center fire, but rim fire............Hence the ignition will settle like a box of corn flakes............

Best I know is a wet mixture is spun into the rim. The wet mix dries before the powder is added. Its like there mayb wasent enough mix put in to start with and it didnt make it all the way around the rim.
If im wrong let me know guys.
Hpoefully C3 will chime in.

But, once it all dries..................Like i said the jostling around in the brick form...............I guess I need to take a fTf and carefully see whats what.............:eek:;)

The priming compound (lead azide) is in the form of a wet paste (MUCH safer to handle it when wet!) A drop is placed in the case, it is spun at high speed, forcing the wet glop out into the hollow rim, where it dries.

Problem #1- it did not fill 360 degrees. Your firing pin hit where there was no priming compound. Misfire.

Problem #2- Whoops! We missed priming that one! Misfire

Problem #3- while the paste sticks well, it CAN be knocked loose. DROP a brick of 22 from table height onto a hard floor, and you may have knocked the priming loose from some of the rounds. Misfire. Prepping for a military match one day, got MOST cross with a PFC that dropped a CASE of Match 22 ammo off the tailgate of a deuce-and-a-half.

So, we should get less fTf with up right boxed ammo that hasn't been to hell and back, and the norm, you get what you pay for...........But, the manufacturer allso comes into play..............problem solved......?????????? It seems that my fathers ammo in 22 cal. never fTf..........Always bought 50 round boxes..............

C3shooter nailed it.. And to answer your question most of the time yes.. ;) just like to add... When ur talking about match grade the tolerances are all much better. Every bullet is with in a couple thousandths of each other and all weight the same or really close. Getting what u pay for. Yes again.. :)

Have u keep any of the shell casings? Make sure that the strikes on the empty cases are all about the same depth and in the same place. If so than and most likely it's the ammo. .22lr are picky as I'm sure you heard.
