While the .700 Nitro Express is a very powerful round, the current 'King of the Mountain' is the .577 Tyrannosaur which was introduced in 1993 by A Square.

The rounds was developed and produced at the request of professional guides in Zimbabwe.  They wanted a newer rifle caliber to ensure that dangerous game was killed in the event that clients missed their shot(s).

Data:  The 577 contains a .585-inch (14.9 mm) diameter 750-grain (49 g) Monolithic Solid Projectile which when fired moves at 2,460 ft/s (750 m/s) producing 10,180 foot-pounds force (13,800 J) of muzzle energy.

That is a lot of force to be contending with. Looks like a fun experience.

Why not use a .50 BMG?

It stays supersonic out to 1500 yards, up to 3,000 ft-lbs of energy at the MUZZLE (max about 15,000 ft-lbs / 18 kilojoules), and surplus ammunition is widely available.

Why re-invent the wheel?

Try the Barrett M82.  I used to make the barrels for these bad ass rifles!

 

Do NOT chase tail. Turn yours around and live FREE!

Check, though I would suggest that we recruit 15-20 men to join us in firing the weapon. This would preserve our respective shoulders and ensure that continuous video footage was being recorded!

Reinvent the wheel ... Ha!  Box magazine, scope, bipod, muzzle break, max range of 4.5 miles ... This is George Jetson's car compared to the humble .577 TRex.

 

In terms of a military weapons, things have certainly progressed well beyond the days of the M-16 (5.56) and M-14/M-60  (7.62) with the .50 BMG round moving away from the WWI era Browning Machine Gun platforms. 

(.223 Left)  (.308 Center) (.50 Right)

The current M82 platform is intended to be used against military vehicles and not individual men.  This of course changed with the advances in weapons, optics and ammunition technologies that are entering the battlefield.
