Of all the pellets you tried out, I prefer the destroyers the best although the gamo hunters have a good "wallup" to them. I wish they Destroyers came in a bigger tin. As for the 100 yard bird,...sometimes it's better to be lucky than good. I'm just happy that you got him,..I didn't see a pix of the bird, but I hope it was a starling or a grackle! From the pix, I think your best grouping was from the Destroyers?!?!? I've taken squirrel from 25+ yards with them. They'll get the job done. tjk
