I found these in Larry's (Alabama) and can't even find specs on them. They should prove interesting!

Springfield XD 4" 1419, 1351, 1402, 1332. Average = 1376 FPS/ 374 LBS
EAA Elite Limited 4.75" 1453, 1473, 1423, 1442. Average = 1447.75 FPS/ 414 LBS
Whenever I can afford to buy a new batch of gel, this will be close to the top of the list. Looks like they are intended as training rounds for use on steel targets at close range.
They were interesting, just a tough plastic inside a brass jacket...I don't think of them as frangible!
