.740 Bore Projectile

[dewey-1]

Here is probably the most ideal, consistent and accurate projectile you could use for a smoothbore home built launcher!

You can not home build one for the price of $.65 each.

This one is for .740 inch bore. (18.796mm) to be exact.
19.00mm nominal size or .748 inch bore.

Here is a link for USA;

Good find, and not that expensive either, 100 for $65 isn't such a big deal (unless you've made an autocannon ) for the dedicated enthusiast.

They will probably leave the barrel of your average pneumatic at a fairly low subsonic velocity, so trajectory could be expected to be a bit howitzer-like at longer ranges, however even at say 500 fps keeping all your shots on a saucer at 50 yards should be no problem with a consistent launcher and reliable sight setup.

Ooooo!!! Those are cool. And I have a new hybrid. Looks like I need a 3/4 inch barrel.
They really aren't that expensive too...

JSR;
You need to try these with your HPA source!

I know, that is to big of bore for you!

If I could still build stuff, I would definitely try some.
Maybe some one else will give them a try and report their results.

Heard anything about these on Box of Truth?

My 0.75" pneumatic was already about the limit I could shoot at home at just 100 psi, I wish I could crank it up with HPA but it would be a project I could never use :-/

Not this particular brand but there's an interesting "rifled vs unrifled barrels for slugs" article

The optimal barrel for these would be 3/4 inch Copper Type K which is the thickwall version.

The ID is .745 inch nominal.

Maybe with a shotgun wad it'll fit the co-ax...Hmmm.

Something to think about, but they are awfully light at only 1 oz.

Thanks for the link Dewey, good find!
