I have an A2 Hannibal that I picked up about 5 or 6 years ago. The cartridge itself is comparatively practical and easy to reload. I had my rifle Mag-na-ported as I can't stand muzzle brakes. Recoil, while stout, isn't too bad until you get over 2400 fps, when the kick picks up something of a snap. I'm good for about 12-15 accurate rounds of full power stuff per session. I've pushed 570/600 grain bullets to slightly over 2500 fps before backing off ...

As you can see, I'm a fan of the Mag-na-porting process. The bottom one is the A2.
