NTW-20 ANTI-MATERIEL RIFLE Link
This anti-materiel rifle is interesting from the two points of view:
- its function and purpose;
- methods of dealing with recoil.

The rifle is built around two cartridges: the South African MG151 20x83.5
mm and the Russian API or API-T 14.5x114 mm. Optionally, and for the
purpose of decreasing cost of training, the rifle can be made in caliber
12.7 mm.

The NTW20/14.5 rifle is an anti-materiel weapon that can have many
applications, including the Explosive Ordnance Disposal (EOD), i.e. in
addition to a purely kinetic effect, the 20-mm warhead is the smallest
round that can deliver a useful payload. Its fragmenting HE capability
makes absolute pinpoint accuracy less vital, since target effect is not
limited to bullet diameter.

I'll take two! Sheesh, guess I can't call me .458 "big" anymore. Oh well. Any more ballistic information on the rounds it fires? I'd love to plug in the numbers to see how much recoil is actually there. Wow!

I think I will stick with my puny inadequate .375 Magnum Winchester Model 70. The only thing which gives me hope is that anything I have ever shot with it promptly layed down and died.
 
Maybe Rich could pick one up on his trip to Africa
