The 30mm x 113 is the ammunition type used with the M230 Chain Gun mounted on the AH-64 Attack Helicopter.

The 30mm x 173 is the ammunition type used with the GAU-8/A Rotary Cannon.
The PGU ammunition is different from traditional stuff, the driving bands are nylon as opposed to the traditional copper or iron.

Well, I’m starting to feel a little better so, this morning I got in the shop and grabbed a piece of hickory that I had used to practice on a few months back. It was almost 12” long, but warped.
I figured I could make something out of it, and decided to try and make a 50 BMG round.
Hickory is nice and hard, but not to hard and doesn’t chip out like so other types of wood.
I didn’t take pics of it before I started turning, it didn’t look appropriate for the forum
But here it is right after I finished turning it and was ready for sanding.
Here it is with a fresh coat of lacquer, next to a 50 BMG Dummy round that @H&R Glock sent me a while back.
And here it is all finished. It’s not perfect, but it’s pretty close.

That's pretty accurate.
I'd bet it's impossible to make wooden links to go with those, but......... I believe the gunny can make a complete wooden M2 heavy barrel from memory that takes down like the original, and fires dowels at high velocity. Some people can make anything.
Nice work Gunny!!!!

You give me to much credit.I'd bet it's impossible to make wooden links to go with those, but......... I believe the gunny can make a complete wooden M2 heavy barrel from memory that takes down like the original, and fires dowels at high velocity.
Nice work Gunny!!!!
That's a 50 Weatherby Magnum. You can tell by the dual radius shoulder, for higher velocity Actually that turned out very well.
Actually that turned out very well.

Nice job on the fifty Gunny.
Here's my attempt at a 9mm. A little fatter and I'm attributing the shortness to set back.

The bigger stuff is easier its actually harder the smaller you go.
I had a bet with a buddy at the shop a couple of years ago regarding trying to turn a .22lr to scale. Neither of us has tried it yet.

BTW Gunny, have you tried any off axis turning yet?
I got one of these a couple years ago and its super cool but will make your cheeks tighten while materials are swinging.

How does this look? Only took 30 minutes.
I think I’m going to stay away from that off axis turning, might hurt myself.

Looks like a yellow jacket.
Yours looks better than the original!

I need to use a harder wood when running smaller cartridges. I need to place an order for some more wood.

Thats not bad! What kind of wood? Kind of looks like Padauk.
I've got to get this piece of Cedar finished before I start anything else. But I'll give a go here soon.
I'm fortunate I don't have to order wood as most of my blanks come from work.

I think it’s Padauk, but not sure. It came in a bag of cutoffs I bought a few months ago.
Free wood. You’re lucky.

I get a lot of my fancy woods from motorcycle and ATV pallets.
You'd be surprised at what they are made from... .

With the way .22's are today, the chances of the brass one going off aren't that much better than the wood one.

I was going to make a golden bullet joke but there really is a better chance that wood 22 goes off then some Remington 22lr lol.

I am and I don't take it for granted. Certainly one of the perks of my job.
Another perk is being able to bring my own material into the shop to work on. I recently acquired some White Oak from my Dad that was milled near the farm he grew up on, from trees they harvested on their farm. Wood is 60 odd years old.
I'll be dressing all of it and making a 7ft dinner table out of some of it.
