Flash Hole Alignment

I've noticed that a percentage of my brass has the flash hole offset within the primer pocket. How big of an issue is this? I've seen this issue with Aguila, Remington, and LC.

does it seem to affect accuracy?

I remember seeing a study done by someone using a particular year of LC M2 brass noted for offcenter flash holes. The conclusion from his testing was: No Problem.

Fiocci factory loads are most accurate and all are notably offset.

GO FIgure!

In addition, the Russians won their boar event in the Olympics with berdan primed ammunition. You can't get much more off-centrer than that.
It might be that in certain cartridges in certain situations that it might affect the accuracy. But logic indicates that it could enhance accuracy as well as degrading it.

I agree it isn't a problem.

Unless the flash hole is so far off center it is setting under one of the anvil legs!

But that would be nearly impossible.

In hand loading for accuracy, consistency is one of the most important elements. If I see an offset flash hole when I square the primer pocket the case goes into the trash pile because the offset may compromise the deburring of the flash hole inside the case.

Then, of course, there is the psychological effect that the "thought" of the offset might contribute to inaccuracy would have while I was competing. :eek:

Paranoia? :confused: Geez, there are folks out there that weigh and sort out individual primers before seating them! :what:

So my idiosyncracy of discarding cases with offset flash holes is acceptable in my little world. :D:D:D

To each his own...

Well like an old AMU Bullseye shooter told me once.
If you think it helps, it helps.

I don't think it helps, but if I did, I would most certainly do it too.

Can I have your scrap?

since you are already shooting at least three different types of brass, the offset flashhole should not have an affect on your accuracy.

Have to agree on this. MIGHT (not my opinion) make a diff if all your brass was the same.

kingmt - Can I have your scrap?

I bought 3 2500-case pails of LC 5.56 once-fired brass in the late 90's. I've used up one pail and the cases with offset flash holes amounted to .5% ~ approx. 125 cases. You can see that they are not worth worrying over.

I've already tossed them, but at my current rate of usage I'll save the rest for you over the next 24 years just for the price of the postage! :D

Somber thought: My widow will probably be selling the bulk of what is left on ebay! :(

Tell her the scrap bucket is mine. I might offer her a deal on the rest of the stuff also. I may be to old for it but I'm sure the kids would like to have it. :D

.......or her new boyfriend might load it up and shoot it himself.:what:

Sorry, couldn't help myself. Whenever I see a post like this, it reminds me of a guy I knew that had several NIB never fired handguns that were his pride and joy. He died young from cancer and his widow remarried. I now see those handguns at the range quite regularly.

Me, from a practical standpoint, cannot see what difference an off-center flash hole could have on bullet accuracy. We're talking being off by only a few grains of powder width. Unless one is shooting a compressed load, the shifting of powder itself in the case would have more influence. But then, I'm a firm believer in if it works for you, go for it.

I've seen that many times myself, but when you're dead it won't matter to you. What does concern me is how folks take advantage of widows, especially those who don't know the value of things. :fire:

I apologize to the OP for some of these derailing comments, so I'll desist and bring this up in another thread.
