Well, I just posted something in regards to this. And I actually posted it in a SD thread. But my quick keyboard fingers got me into trouble. (Not really, but I sure did feel stupid)
Anyways, I recommend staying away from the Federal Champion brand at Wally World for your 9mm. It's worst ammo for accuracy I've shot since I've owned a 9mm. Reloads included! It's a great price (8.97 for 50 rnds. I think) But me, in my SIG Pro 2022. Which tends to be very accurate for me. Was horrid! Luckily I picked up some Blazers the morning of my range visit. Popped them in... just like clock work dude. Night and day, period...
Now, on another note. I did get my hands on a boat load of it for my .40 s&w. It doesn't seem to be a problem for me in my S&W model 410. Also, the gun I'm most accurate with.
I'm no Billy The Kid, don't get me wrong. But puttin them in the paper anywhere up to 25 yard has never been much of a problem until I experienced this 9mm round. Good price or not, I'll never purchase it again. But I will grab more of the .40 stuff when and if possible.
I say try it in "your" weapon. What do you have to loose? It may run totally different in yours. I hope so for your sake. Maybe if you can get ahold of some maybe fight your urge and only get 2 boxes instead of 6. LOL
