"Will someone please dust off their college physics and tell my why the .950 can sustain a rate of fire of approximately 1 round per minute while the A-10 can sustain a rate of fire involving 4,200 rounds per minute using a round with approximately 3 to 8 times the energy."
For starters, the Warthog that it's attached to weighs something like 30,000lbs and is traveling 3-400mph at the time of firing. Electrically driven 7 barrels means each barrel only sees 1/7th the actual fire rate, electrically fired cartridges mean now mechanical firing delay. Forward airspeed rams large amount of cooling air to barrels. End result---don't get a Warthog driver mad at you!

This cartridge is not so interesting after seeing it is necked up. If on the other hand it was a 20x102mm that was necked down to accept a 50 caliber bullet, that would be interesting. The rifle could be as scary as one desires and ATF would have to suck wind. Plus it would be more useful as it would have a smaller cross section thereby better aerodynamics.
This particular round doesn't excel in anything. You can't use it for a long range round, it isn't particularly accurate, it isn't cheap, it doesn't have any more kinetic than a 20mm, it doesn't penetrate very good. All it does is kick like a mule.
Also, the 50bmg can be regulated by the ATF if they want to push it. Only the barrel is .50 (measured from land the land) the projectile is a bit more.
Yep, but you do realize that the bullet is over .5 inch to make a complete gas seal in the grooves don't you? The ATF says they measure the bore of the gun but don't say where at. The lans of a .50 bmg is close to .50, so the grooves would have to be a bit more than .5.
I was under the impression that any rifle having a bore exceeding .50" qualifies as a "Destructive Device" and is a Class III weapon, making it mandatory to have a BATFE Class III application and $200 tax stamp approved to transfer.
Does that include my compressed air spud canon?
