those are similar to these as well JSR


simple but effective aye

i might see what i can make up with some sheet metal and a piece of 8mm cro-moly rod

They've been playing with the idea of flechettes for small arms for quite a while now - while it would be an outstanding penetrator of body armour, there are doubts as to how effective the tiny diameter (even less than the 5.56 round that soldiers already complain about) would be against living tissue, as well as accuract issues of fin-stabilised rounds from a smoothobre barrel when compared to bullets from rifled barrels.

wow those are the coolest things i've seen in quite a while. What and how are they fired?

One of these.

And also These:

actually the one fired by the AMR is on a somewhat larger scale:



compared to a 7.62 NATO cartridge



cutaway view

the calibre 15.2mm, almost three times the SCF, and the tungsten dart can penetrate an incredible 40mm (a little over 1.5 inches) of steel armour from a kilometre away

feck, forgot that site doesn't allow hotlinking. You can see them here.

You might also find this of interest, it's an well written article on the history of high velocity projectiles (great site too if you have a browse)

I've worked on discarding sabot darts.The problem I had with them was at higher pressures(100psi on up) they started to get a little wobbly in their flight pattern.I built them with ring nails and sheet metal fins in a foam sabot.I also did it with darts that had string on the back,same issue.I had to bump the pressure down to 60 psi. to got them to fly straight.

I've become really cheesed off by my nail darts.

At 240psi what I usually end up with is the tail section leaving the barrel, FOLLOWED by the nail tumbling out.

Seems to work to 100psi though.

I may make some solid tail sections to replace the thin cones I've been using for tail drag so far.

have you tried hammering the head flat as a fin?

I agree with mrcrowley... it is B-E-A-utiful. Jack do you own that? cause it looks like you took pictures of it on your kitchen floor.

Jack, where do you work?You seem to know an awful lot about military arms.
SPAWAR or the like?Heck, you know more than me about guns and that's not fair.I need to know what proffesion to get into.

Not like I'll learn very little about guns in the Marines

Much as I'd love to have rods of depleted uranium running around my kitchen sadly I cannot claim ownership of the round.

I work in a laboratory for a pharmaceutical company, not really arms related (unless you mean making your arms feel better :p) though we do make cannons out of the pipe fittings in the plant - I'd post videos but I don't want to get into trouble - still, always had a passion for anything that produces recoil or torque and I do my research well
