Ok so I picked up a E Series last week. I have put 40 rds of Federal Premium Hydro-Shok through it 50 rounds of blazzer brass and 350 rounds of blazzer aluminum. My second to last box of blazzer alum had 2 FTF with it but then fired 16 rounds of hand loads from a buddy and another 50 of blazzer alum with no problems. Do you think I should just through those 2 out as being the blazzer alum quality? My tendency is do that after 448 good rounds. I hate seeing any issue in a gun that I plan to carry but I guess they all can have that occasionally. What's your thoughts?
