45 ACP case flash hole revelations

[Matt Anthony]

I've been shooting and reloading for over 55 years and recently I have seen something that is disturbing. I was reloading 45 ACP and cleaning the primer pockets when I noticed a Winchester case with a huge flash hole. There was just enough material at the bottom of the pocket to stop the primer from falling into the case. Sorting the different cases, I noticed that there were Federal primers also with huge flash holes.
I checked all 1450 cases and came up with 33 Winchester and 14 Federal. These were once fired cases taken from our range. They looked absolutely new!
Anyway, I was thankful I inspect every case as this could of been a bigger problem if these cases were fired.

I've seen a few that I picked up at the range. I think they were from ammo listed as enviroment friendly or some such nonsense.

I remember back when , when CCI ( I think ) made plastic bullets to be powered by a primer for indoor practice . The .38s had thier own little plastic cases , but the .45s were to be fired in standard .45 cases with the primer hole drilled out . This somehow prevented primer set back in the primer alone powered loads. this made the cases unsuitable for powdered power loads.
The " green " loads , AFAIK , are all small primered and normal sized holes and have TMJ bullets , although they advertise them as FMJs.

Could you be picking up one person's brass who is for some reason drilling the holes? (All found on same range?)

Chris is right I think. It was standard practice years ago to drill out the primer pocket for a load that could be used indoors or down in the basement. Many loaded the case with a wax bullet powered just by the primer.

Before getting too worked up about it, I'd take a couple of those cases and load them up and shoot them to see if it really makes any difference. I can't imagine that a standard LP primer lighting 5 grains of BE or 8 grains of Unique will show any difference at all.

I am not worked up at all, just posted a warning to watch for enlarged flash holes. These cases are once fired from Winchester and Federal. They have not been drilled out and both loads were standard 230 gr. full metal jacketed. Like I said in my post, the Winchester cases do not have enough material to afford to even install a primer.

Here, let's not get too far into this event, a flash hole is suppose to be no more than .080 and some cases have even smaller diameter flash holes, like the PPC's. Higher than normal pressures will happen if the flash hole is larger than the standard. And yes, wax and rubber bullets used for indoor shooting will require you to drill out the flash hole and you must keep them separate from standard load cases.

That's it, if you want your ammo to be consistant, then your brass must be consistant! From the length, sizing, primer depth, flash hole burrs and diameter to crimping, everything must be uniform.

When you use words like "disturbing, "problem", "warning", I get the impression that you sense something terrible is about to happen. My post was meant to suggest that maybe there is really nothing at all to be concerned about. As I suggested, load up a few and shoot them. You may find that you really cannot tell the difference. I shot my first pistol competition in 1955 and have loaded thousands of rounds of handgun ammunition since then. I have yet to find that prepping pistol cases or trying to load for maximum uniformity makes any difference whatsoever. Maybe your experiences are different. I also shoot Benchrest and agree that such things may be important in a cartridge like the PPC that generates 60,000+ psi chamber pressure and is meant to shoot tiny dots instead of groups, but not in a 10 - 15,000 psi handgun cartridge where 5 MOA will win you all the fake-wood trophies your den wall can hold. The age of the Internet has caused many shooters to become overly anxious about things that we used to consider routine.

I have some Federal Champion cases that I kept after shooting; I can pass a 6/64ths drill bit through them but not a 7/64th. I have some new Starline brass that I can pass a 5/64th, but not 6/64th.

Ray, flash hole diameter is important and it can be extremely dangerous for the shooter and others around that shooter if a load blows up. I posted that there wasn't enough of the bottom of the flashhole to even seat a primer and you say, "load up a few and shoot them". I will post a picture on Monday as they are at my business. The fact there is no meat at the bottom of the case to support a primer was actually more of a concern than the increased size of the flash hole.
I follow instructions the manufacturers print, the information in reloading manuals and follow safety concerns about reloading cartridges. There must be a line drawn by all reloaders to adhere to standards when reloading and shooting any reloads.
Was this alarming, disturbing, a problem and a warning, well yes it was. As something I noticed when I was sorting cases! What is wrong with posting what I experienced and warning others? Well Ray, there is nothing wrong with what I posted, however, you poo-poo'd my post as nothing and for me to load up sub-standard cases and fire them. That is totally irresponsible for you to post something like that, in fact I am shocked that you would tell someone to "load them up and fire them"! What, to see what could happen............incredible Ray, simply incredible! What if I had done what you suggested and my 45 came apart and blinded a bystander or part of my 45 shot through my neck cutting my carotid artery and I layed there as my blood ran all over the range floor, ruining everyone's day and then I expired! Thanks Ray..........
However, these cases are not NT cases, which do have larger flash holes due to the Non-Toxic primers Winchester uses on NT cases.
