It's just a preliminary step before seating this same bullet in a composite case, the ultimate goal is to be able to launch a lead-free bullet with a C7 CB above 0.20, at a MV around or above 850 m/s from a 14.5" barrel (so slightly better ballistics than a Mk262), with a cartridge weight below 9 g

That'll be wonderful if it comes to fruition, and I sure hope it does.

Thanks for giving us the project update.

Composite as in hybrid plastic and steel?, is that possible for your lab to do, or will you have to partner with TV?

It seems the Neckless concept is gaining ground. TV has now debuted a .338 Neckless:

.338 TV

.338 seems to be the perfect format for this, in that weapons have not yet been fielded, so theres time to have chambers re-cut for neckless as opposed to .338 brass conventional.

Trouble is, whether neckless or necked, a .338 machine gun seems to be a solution in search of a problem...

Yes, but if it can serve as a fielded test bed for neckless ammo that’s at least a win for ballistic science, which is about the best we can hope for.

Right, even if a neckless .338 Lapua will do everything (and even more) a .338 Norma is supposed to do.

Yep.

We have contacts with EU industries that are willing to invest into this technology, but at first we are going to do this study "in house" because it's not really mature enough.

We need also to investigate cold-pressed bullet manufacturing that will include steel core, instead of all-brass machined bullets.

Er, 6.8 is .277, not .338. Waiting to see if one of the budget rifles gets chambered in 6.8.

You're right.
