Freedom munitions. I order their "blaster training ammo" because it's a little cheaper. The cases may have some dings in them, but I haven't had any issues with the ammo.
Plus they have a 5% off coupon until the 11th (I think).
1000 rounds for 299 (plus delivery). I ordered 250 rounds today for $75.

Just ordered some. It did not say how long it takes to ship. Do you know how long it normally takes and have you tried out there 9mm rounds.
