I usually buy a ten pack of pellets when I get down to a couple three tins left. After I see what my gun shoots I stick with that pellet. I have seen the 10.3 JSB heavy I am looking for hasn't been available. I notice a few dealers have what they tell me is the same pellet in FX of Daystate. My question is this. Does a JSB FX or Daystate 10.3 diablo shoot consistently the same as in if you just have a different lot # I am not actually asking for the best just do they compare closely between these brands?
