I would say minimum 40 years old. Probably older. I would hazard a guess at 50.

Etymology of "bullet"

bullet (n.)

1550s, "cannonball" (a sense now obsolete), from French boulette "cannonball, small ball," diminutive of boule "a ball" (13c.), from Latin bulla "round thing, knob". Meaning "small ball," specifically a metal projectile meant to be discharged from a firearm, is from 1570s.

Is this why some ammunition is referred to as `ball` ammunition i.e. .303 for aircraft or is that something else?

It's just a bit of junk in the bottom of an old tool box. And yes, probably .303.
Whatever it is, it is most certainly not a 303 projectile! Or a cartridge either.

Loaded (and fired) enough of them over the last 40 or so years!

Which reminds me; The local Rifle Club is having a special 303 shoot over the Anzac Day weekend. I'd better get my press set up and load a few!

So, what do you think it is, Pinky? The size looks right, and it looks as if it was in a jacket. Hard to tell without having it in one's hand, I know, but I'm baffled as to what else it might be. I don't load in that calibre, so haven't anything to compare with it. Could you share a photo of what you load, please?

No. "Ball ammunition" means the projectile is metal-jacketed to prevent the soft led core expanding or fragmenting on impact so that it makes a clean wound, as opposed to the soft-nosed hunting ammunition that is intended to expand and fragment to increase the chance of a kill.

Piper.Classique; I really have no idea what the mystery object is and nor can I post any photos of 303 rounds, as I have no idea on how to upload photos taken on my phone.

However, I can say with authority that the object concerned is not a 303 projectile!
The standard MkVII 303 projectile measures .311" or approx 7.7mm in calibre and 1.286" or almost 33mm in length. The mystery object pictured is of greater diameter and length than the 303 projectile.

As for the loaded cartridge; once again a MkVII cartridge, in this case an FN manufactured round is 3.37" or just over 77mm in overall length.

As I type this I have an example of each on my desk, along with a set of Dial Calipers.

Re the photo of the four 303 projectiles posted by munnst: The band about the middle of the projectile is not a rifling band! It is a cannelure in the projectile and when the round is made at the Muntions factory, the projectile is inserted into the cartridge case to the depth of that cannelure.

The case neck is then machine crimped into that cannelure to ensure that the projectile does not work its way loose from the cartridge case, which can otherwise occur when the rounds are in a magazine of an automatic firearm and be subject to some fairly vigororous fore and aft movements.

Just looking at those four projectiles; None of them appear to have been fired. Otherwise there would be striations on the projectiles from the rifling in the barrel, which would be apparent from the cannelure back to the base of the projectile.

Was your father a HiFi buff by any chance? It occurs to me it could be one of the adjustable point-contact speaker/turntable feet that were a fad at one time.

is metal-jacketed to prevent the soft lead core expanding or fragmenting on impact so that it makes a clean wound,
Which incidentally, is something that the MkVII 303 projectile did not do! It had a small 'nose cone' inside the jacket, made in the case of Australian manufactured ammo, of aluminium. This made the projectile somewhat unstable after entering a body and it tended to tumble thereafter!

Could it be something like this but from the old wooden versions that used to be about.

All the old wooden ones I used had larger metal feet that fitted over the wooden legs.

Unfired on the left and the following rounds were shot into sand with increasing powder charges. You can see the rifling striations down the sides of the fired rounds. .

Question

munnst; Just bringing this thread back to the top to ask; Have you discovered just what the object is?

9.53 mm is .375” which is a fairly common big game caliber. Once you cleaned that up, it looks a lot like a jacketed bullet with some of the copper case peeled off. The groove around the middle is likely a cannelure (where the bullet can be crimped into the cartridge case) and the lengthwise scoring might be rifling marks indicating that it was fired into something soft enough to not deform the bullet significantly.

parenthetically, “bullet” is used on this side of the pond very often as a synonym for “round of ammunition” as in “I’ll be right back, I’ve gotta run to the truck and grab another box of bullets so we can shoot another round of skeet”

Everyone knows full well that the speaker is referring to a box of shotgun shells, which don’t generally contain bullets...

421dog; Re your post; I must disagree as to it being a projectile. To be rifling marks,the lengthways scoring would have to be at an angle to the 'projectile,' and in this case they do not appear to be so. Rather they appear to be very much 'fore and aft.'

I continue to think that it is not a piece of ordnance!
