Is this a bullet, artillery shell?????

[ponchh]

This is what the real thing looks like. On a live round a few inches would be cut off the nose to screw a fuse on. What kind of powder would you use for this.

 

[Vern Humphrey]

You see also the base plug. This is where the shell was filled with explosive and where a base fuze would be screwed in.

Rotating Band = Driving Band

An "Obturating Ring" technically does not impart rotation to the projectile, and is what is found on mortar projectiles (except the 4.2 inch) and fin-stabilized, discarding sabot rounds fired from rifled bores.

You beat me to it. I started in the artillery in 1968 and since them referred to it as a rotating band. I've also heard it referred to as a driving band.

A friend who spent time in R&D in artillery told me obturating band is really a gas seal as in mortar or discarding sabot smooth bore rounds. A rotating or driving band engages the rifling and obviously forms a gas seal also.

While the terms technically mean different things as far as engineering goes they are pretty interchangeable in common usage.

"Driving band" is more often seen in British manuals.

Seven perf, M1 most likely.

Although, that looks like a dummy projectile, having been fired, but still in one piece.

It could be used by a RR mechanic to center a locomotive axel thru a bearing and wheel. Jack up the locomotive, use sledge hammers to pound the centering cone and axel thru bearing and wheel until axel is flush. Probably used for a repair, left on the locomotive by mistake and dropped off during a run. Just a guess, but far more likely than a shell.

yeah there aint no fuse on that boy and it i dont see rotating bands. to small to be a 155 and doesnt look like a 120. So idk.
The issue of not know about general no movers are if you can't identify the fuse, if its a cock striker with the fused damage (would make my booty pucker), grey sensitive fuses and the likes. Basically if you are not EOD, leave up to the people who get paid to play with UXO before touching it. Don't be a hero, don't try to render safe, don't consolidate it to a "safer area" just martin baker the hell out and call it in to the PD/Sheriff or whatever.

Reading the tape in the photos in the OP, this object is 8cm x 20cm±, or right at 3.14" x 8"
and appears cast and not worked or machined.

It is a 105 dummy round that they let me have when at Ft Sill

Probably not Bullseye.

Monkey, I'm assuming most of your service would have been with the 155mm guns, and I feel stupid for never wondering about this before, but were they rifled? If they are smoothbore, that would explain why they use obturating, rather than driving bands......
I think CapnMac is on the right track for the OPs question....but shells for those guns would have a charge cavity and fuse, no? Which would mean that thing could be dangerous.....

I actually served on every piece the Army had in the inventory when I was in but mostly on 155/ 8 inch. They were all rifled and according to the -10 the brass band around the base of the round was called an Obturating Band. The firing mechanism in the breech block was called an Obturator Spindle Head. As a side note after I got out of the Army I worked in a factory that made bore brushes for 155s

No. 105 didn't use "base fuses" unless the round was base ejecting (Smoke, Illum, DPICM) the boat tail base was one piece

The powder is Nitro Cellulose. It looks like rabbit poop and comes is separate bags. On a 102 they look like a string of numbered tea bags. You pull the bags (increments) you're not using off and keep them in a separate pit. Then when the unit moves all the excess is burned.

And no, that round was never fired. The rifling on the Obturating band wouldn't be that clean

Not in your time, but base fuzes were at one time used in all calibers.

Not in that rounds time either. You were wrong Vern own it.

 

[Vern Humphrey]

The 105mm had base fuzes although not in recent times.

 

[Vern Humphrey]

I mis-spoke. Here's a modern 105mm with a base fuze.

Yeah, that's a Tank round we're talking artillery. Do try to keep up.

Have we formally determined what this shell is?

However, tube artillery also has anti-tank rounds, including HEAT and Squash Head.

Understanding that my information is old in the 15 years that I did artillery they never had a specific anti-tank round.

What year did you graduate from Fort Sill over there Vern?

I graduated from the Field Artillery and Missile Officer Candidate School on November 23rd, 1963, the day after Kennedy was killed.

Final thought.

In my experience the US military doesn't have any solid metal artillery rounds. They also don't have any rounds with no fuzes.

The diameter is too small for any TUBE artillery piece I'm familiar with.

I don't think it's an artillery round. YMMV

When I lived in Egypt in the mid-50s, we used to visit the battlefields all the time. There was all kinds of ordnance lying around. "Shot" was common -- basically a solid steel projectile with a small charge and a base fuze. Anti-tank guns as small as 37 mm were quite common.

You may well be right.

I went thru school in 1973 and every round has a fuse on the nose that has to be screwed in. Went from gun school to Lance missile school a few blocks down the road and played with nukes for a few years. View attachment 761130
