While these first-gen FCS look bulky, this is single greatest upgrade to lethality

I imagine Elcan being free of ITAR will corner large chunks of the market.

Quick question about the textron 6.8.... am i to understand that only CT rounds can use compressed propellant?

Or could it be used elsewhere -for example- to reduce the size of a 556 round?

And can compressed propellant be combined with high case pressures?

Thanks

5.7x28 is bottleneck.

Does being a bottleneck have any real effect on feeding reliability when we're talking about pointy, Spitzer projectiles? 

I'd get the benefit for pistol rounds (.357 sig vs .40 using flat tip JHP) but for spitzer, the pointy tip is so much smaller then even a narrow .224 opening that I imagine bottleneck is pretty irrelevant.

Is that smart optic you're showing the new 'Smart ELCAN?' I had heard they were working on one but have never seen any specs or news on the project since.

Technically you can use compressed propellant in anything so long as you're using the right propellants.

Yes it's also compatible with High pressure though it's best to keep in mind that the higher you run your pressures the more similarity your cartridge has to a bomb if something goes wrong.

You definitely want to make sure that the guns action is rated to 25-50% more pressure than the peak pressure you want to run.

Going back to the safety aspect, if one had a TKB022 or steyr ACR with NGSW ammo, surely youd need a lot of steel round the chamber to protect from kabooms...

as for compressed powder, im surprised noone has tried to reduce 556 down to 5.7x28 size.

also the 4.6hk has 65k PSI as well.

I wonder if reverse feed guns like the PKM or boberg pistol could cope with ultra pressure ammo....in principle i mean

Somebody has, and it's been posted in this thread!

Gatnerd showed the Knox engineering design. I'll repost just so you see.

As far as needing "lots of steel"... Not really.

You need to use very good steels and well optimized bolt head designs or etc.
