I understand, you must be a little frustreted huh? There is nothing quite so uncomfortabe as the knowledge that your gun may not fire! I hate the feeling and cannot rest until I fix it somehow. I hope you get to the bottom of it and will be interested to hear what happens. By the way, I have used a lot of Range ammo (magtech) and have not had any prob's so it may not be the ammo. Anyway, best of luck to you and I hope your back out firing away very soon.
