First thing you need to do, Al, is toss those pointed pellets in the trash where they belong :-). I've NEVER had good results with any pointed pellet in any gun. And that any runs the gamut from low powered springers to high powered PCP's. I don't have a Blizzard, but from what I've been able to gather, it's a hammer, so concentrate on the heaviest pellets you can get, either Kodiaks or Eun Jins. Part of the problem is probably just too much velocity with the lighter pellets. Don't know what to say about your magazine issue, maybe Joe Cuz can help out there. Good luck.
