ISO “Armor Piercing” Ammo (air quotes)

Try these. My Taipan Veteran is chucking these at 900 FPS with very tight groups at 50 yards. Great 25 caliber slugs.

 
Everyone suggesting slugs when the man has an armada. Basically an Mrod barrel. They don't usually do well with slugs. Hybrids may be an option, but the 25s are on the slow side in stock form.

I vote baracuda if the gun will shoot them, my jumbo loves them and slings them over 850 fps. Other option is polymag or metal mag.
