I have tried them in nearly a dozen different spring and pcp rifles and they are the most inaccurate pellet I have ever shot. I think it is because they are 4.51 diameter. This is particularly interesting to me as the .22 version is extremely accurate in my Air Arms S410 and Weihrauch HW 80. However they are full bore sized at 5.52.
Label on the back of tin say 4.5 mm on all mine - ditto can't hit anything with the .177 hades in any airgun at any speed, same airguns shoot really nice groups with the JSB heavy of same design minus the imprint in the head
Most of my airguns have choked Lothar Walther barrels
JSB should redesign the .177 hades IMHO
On the other hand, the .22 hades (back of tin say 5.5 mm) is shaped like the JSB Monster redesigned and group just as well as the JSB exact in 5,52 mm.
