.45 flash hole size - NEED HELP !!

Iconoclast

C'mon, with all the people who shoot .45 here, no one has these on hand? <snivel, whine> [;)] 02/19

All my gear is packed away, so there's no easy way I can check this on my own.

Would one of you folks who has some fired US military brass at hand - preferably pre-war and / or WW2 vintage - measure the size of the flash hole for me? *Not* the pocket, but the hole going into the body of the case.

I picked up a large amount of material which came out of Aberdeen. Among it are a few inert .45 rounds which I dismissed as junk at first, but looking more closely, I'm wondering if perhaps the flash holes are larger than normal? The date (42) corresponds to a time when FA, especially, was conducting experiments with primer mixes which would be compatible with the powders they wished to use to supplant Bullseye . . . makes me curious if this might have been an experimental lot of brass. For sure this was the way the holes were formed, as the cases are plated (another unusual feature for this period) and the coating is on both the interior edges of the primer holes and portions of the inside of the case walls.

You gotta be kiddin' me - nobody has any of the older military brass kicking around???? 02/08

I MIGHT? be wrong in this, but in the past the information was circulating that nickel plated brass was specifically used for proof loads, i.e. so that no imbecile would get his hands on them and try to shoot them out of his 1911.

If this is the case?, your nickel plated brass might be special production stuff with variant dimensions.

Y, nickel plated cases are often the way the military identifies High Pressure Test (why use one word when three will say the same thing?) rounds. OTOH, I've been collecting US military ammo for about 35 years and when one is dealing with prototype / development / special project items, the standard practices tend to be observed from convenience rather than as a matter of policy. Frequently this is because the markings are for some internal project and everyone handling the material *at the time* knows exactly what it designates. Another reason is the parties involved have shown a tendency to grab whatever is at hand which will work. The only time it becomes a headache is when some poor collector or historian is trying to ferret out the details years later. Naturally enough, this is not a major (or even plain "a") consideration to the experimenters.

[8D]Yo Icono, No I don't have any Military .45acp, but by measuring my Winchester shells it looks like .77 thousands avg. Guess what? I'm still using my "Flash-hole" measuring tool from "HERTERS" CIRCA 1965 [:p][:p][:p][:D] JIMBO

On your mark-get set- go away!!

[8D]OOOOOOOOOOPPPPSSSS, Sorry I mean .077 thousands of an inch flash hole. I just got back and read my numerical mistake[xx(][xx(][xx(][:D]

On your mark-get set- go away!!
