For the 6x44 mm, what made you choose the 6mm Unified projectile ?
In what way is it superior to a scaled up 7N6(M) projectile ?
It's a bit like a scaled up 7N22 projectile. But I used it simply because I was playing around with it at the time. Far better bullets both I have designed since and have been manufactured commercially.
Here it is compared to its parent design, Archangel:
Bearcat can accommodate rounds about as long as 2.43", and case heads as wide as 0.473" at up to 75,000 PSI operating pressure (~85,000 PSI MAP).
Currently working on the magazine body for the 760 Bearcat, a reference round that performance-matches M80A1 using COTS projectiles:
The 760 Bearcat:
Despite producing 2,800 ft/s with a 130gr bullet from a 13" barrel, the Bearcat weighs just 4.78 lbs unloaded. Fully loaded with the following equipment, it is nearly a pound lighter than the combat weight of a current US Army configuration M4A1 Carbine (image of representative carbine after the specs):
Vortex Razor 1-10x24: 1.34375 lbs
Scalarworks 30mm mount: 0.3425 lbs
NGAL: 0.3 lbs
Brevis II Ultra: 0.46875 lbs
BFG Vickers sling (unpadded): 0.264375 lbs (0.120 kg)
QD mounts (2x): 0.119375 lbs (.0540 kg)
30 round Bearcat Magazine, U/L: 0.3969 lbs
30 rounds 7.62x41mm Bearcat composite case: 1.053108 lbs
Will it be cheaper than a Wilson Combat 7.62x40?
It's designed to be pretty cheap. You can't know the exact price until you've quoted all your distributors and stuff, but WAG it's not unreasonable to expect a unit cost of $1700 per on the open market. Most parts are made of castings, extrusions, or injection molded polymer. The barrel's the most expensive part, I bet, since it's a composite steel-aluminum dealie.
Gee! That is a big bullet!. I measured it on my screen and it is about 100mm diameter! :0
Does anyone know a simple way to shrink the pictures down so screen-size? I damn near get motion sickness from panning around the large image trying to see the whole thing.
Thanks! Much better.

By casting i assume you mean the receivers? why cast instead of hammer forged like a standard AR receiver?
