I shoot a lot of airguns, all types, all cals. including with slugs and my own cast pellets, but today I am writing about tests of the Hades pellet from prolly the best pellet maker, JSB. The gun used is a very accurate springer a HW97 in .22 cal. the only Hades pellet cal. to date. My best pellet to date is the H&N FTT at 14.66 grains, groups with the Hades did not equal the H&Ns but were close. The H&N pellets were a much tighter fit in the chamber and I believe that is the diff. as the hades were 5.50" and the H&N were 5.52". On ground squirrels the Hades did mushroom a small amount but did not fracture as they were designed to do, not enough velocity I believe. My next test down the road will be the Hades pellets in a higher vel. PCP at around 900 fps. Vel. from the spring powered HW97 was an avg. 690 fps. So if you have a PCP in .22 and want a frangible pellet for hunting, these new pellets may be your best bet.
