I've got my home tuned custom stocked Discovery shooting better with a barrel change and crown polishing and I'm thinking of hanging on to her for my squirrel rifle . All bench testing was done at 18 yards off a single front bag . It's shooting JSB 8.4g pretty good , ragged holes and I'm getting 30-32 shots at 855-890fps. I tried some Kodiaks and they were not quite as good but still a ragged hole most of the time and shooting about 800 fps for 15fpe . Then I tried some JSB Predators and they zipped through the chrony at 900-915fps for a 15.1fpe .And the best part is, when I didn't mess up and pull one off , they would go into the same hole . OK , those of you that have used these pellets for hunting ; should I stock up on the Predators? Or Kodiaks ? Does the few grains of extra weight make a difference? Or should I just hunt with the JSB Exacts 8.4g? Oh yea , and The rifle shoots superdomes into a group about the size of the Kodiaks , probably a .40 caliber ragged hole. kirby
