hehe epic! any ammo ideas for 63.5mm barrel other than tennisballs?

Can you make .177 cal?

See if you can find a tin can of that size (2.5 inches should be a standard size) et voila, a sabot that lets you shoot almost anything

Can you make .177 cal?

It's possible, but a little pointless in terms of performance when so small in my view.

I reckon a needle in a .177 bore would be pretty nifty

Those sabots look pretty good, but stop teasing me with machining gear, only a week to go now... Fuck I'm excited

You can see my work at around 5 minutes 5 seconds into the video... not being shot yet though, can't wait to see these things fly!

i think that i would like to try one with the dart gun i am building how much does it cost for almost a half inch size im nit yet sure of the exact size
i am going to compare it to some other desines and see if it is worth itit is up against

• cone backed darts
  cilinder block darts in other words taped up layers
  and sabot rounds of various types
  maby a saboted .270 cal bullet

i should be like demolition ranchand have some vids of this
i also have another question would you be able to make a molds for lead bullets not the round ones i mean like an actual boat tail round

Your humble scribe gets a mention at 7:30

Unfortunately it did not perform as planned, it seems the light weight prevented the propellant from burning completely.

So it hit dead on, just lacked power?

The armour plate did look pretty tough.

i wonder if you made it out of lead would that make it work right or another heavy material

Turns out lightweight "high velocity" rounds in a shotgun which relies on slow burning propellant are not the best idea...

Also, the steel came from a printer, not exactly hardened stuff.

The same sort of steel I used here.

From this:



to this against steel plate:

Lead is too soft, as you can see in the video he used a lead slug and no penetration.

Tungsten carbide on the other hand...

Tungsten is quite awesome.

On a sidenote, a friend and I are experimenting with powdercoating lead-cast rounds, mostly .45ACP. A cheaper alternative to jacketing.

Interesting... is it strong enough to hold the bullet together while at the same time soft enough to bite the rifling?

Cast lead bullets (boolits ) hold together perfectly with no gas check up to about 1600fps or so, and I've heard 2200fps with a gas check. ¹

Powdercoating works quite well from what I've heard on Cast Boolits, fouling would be interesting to clean though.

Shotgun powder likes a heavy load, burns better under such conditions. He could reload with a faster powder, like red dot, but you'd be better off increasing the weight to at least 20 grams, which is about the limit for significant power with stock shells.


¹ Gas checks are a little bit of Al sheet punched out and fitted to the base of the bullet to prevent erosion from the gasses.

Yeah, at less than 15 grams these really were too light.

I ordered these 3/4 oz tungsten weights and these 7.1 x 100mm HSS rods (craving tools lol!).

No lousy armour plate is going to get the better of me!

sorry i ment put a hardend steel center with the lead as a fin shape
