New to reloading

That close distance would likely explain the chrono reading of 1554 FPS.  Not trying to beat up on anyone just help everyone to understand things based on the info you and others experience and present.

I think you will find that your other cartridges will be within proper range with your powder charges.

I was kind of wondering about that number because I thought Berry's recommended not to exceed 1250 fps on their plated bullets. Because that velocity might shed the plating and cause inaccuracies.

Hey Shadow,
So at 10-12', your readings will be the most accurate, correct? A friend of mine is getting a new chrono, and has offered me his old one for next to nothing. Not sure of the manufacture or model, but hey, the price is right : )
Thanks

It depends on the particular unit and sensors, but most say 10 to 12 for pistol so as not to pick up particulate to start the timers.  Rifles need about 12' to 15".

The Lab Radar is a different system as it tracks the bullet in flight to target by radar and is not affected by the light sources, blast and particulates that can affect other units.

Great, Thanks!

So what exactly in the reloading process could cause hangfires/misfires? Bunk primers,dirty primer pocket, primer not seated properly,C.O.L or a combination of these? I got about 15+ misfires in 200 rounds.
I don't think it's the gun because I ran 2 magazines of factory ammo with no problem.






Edit:hangfire to misfire

I'm no expert to be sure, but sounds like a primer issue

Here are the offending cartridges.

I'm using Fiocchi large pistol primers. Does anyone else use these?

[Graybeard]

Could be hard/bad primers. Could be they weren't fully seated. The one on the bottom right has the biggest dent in it and certainly looks like it should have gone off, I'd lean towards bad primers. I've had the same experience with Fiocchi loaded ammo many times. Recently a rented XDm wouldn't ignite 6 or 7 Fiocchi 45s for me. I loaded them in a Kimber 1911 and they all went off.

To be fair, I've also had a batch of CCI small pistol primers do this. I'm working through those as plinking ammo right now.

[sqlbullet]

Did you try a second strike on any of these?

Doesn't go off with one hit, likely a primer not seated properly.

Doesn't go off with two hits, then it is likely a bad primer.  Which can be too hard, or just a dud.

[The_Shadow]

Recently Intercooler had some primers that didn't ignite even after I tested using my pistol.  When I pulled them down it looked like the priming pellets were loose and crumbling.  The result was no priming mixture where the anvil was to get started.

His was Fiocchi Ammo

[FlyingDtnt1]

I ran most of them through a second time only a few did not go off. I'll be more wary of making sure they are seated properly. I am going to make the switch to Winchester primers, going to pick some up Friday. I still have about 1,200 Fiocchi primers left, lol.

[Kenk]

Yep, gotta always watch for these hangfire's, I have not had this happen personally, but will be on my guard for them for sure

[Trapper6L]

Primer strikes look mighty light to me. Have you had any custom work done to that Glock, assuming you bought it new? I couldn't find the materials used in the Fiocchi cup to tell you if they are hard or soft. Not all primers are easily set off with Federal being the easiest due to their being the softest. You might also measure with a caliper the actual size of the primers, especially the height. If the cup is short, you're going to get light hits. Here's the SAAMI chart on primer sizing.

[The_Shadow]

There can be several reasons for light primer strikes, short casings with extra headspacing and cartridge movement with the strike.
Firing pin or striker channel having debris inside, this can be carbon fouling, dry oils or grease, plating from primer cups or from primer smear from previous loads.
Also as I mentioned above there may not be enough priming mixture between the anvil and the base of the primer cup.  This can be from shrinkage, broken or crumbling priming pellets where the mixture has moved from its original  placement.  Although rare, it is possible for some mixtures to move during vibritory cleaning or packaging or shipping.
