I received an email from Federal Ammo introducing custom ammo for rifles and shotguns. Rifle ammo is $99.99 for 20 rounds. Shotgun ammo includes 410 to 10 gauge and runs $93.95 to $153.95 depending upon gauge, these are 10 round boxes.
Federal at least asks about the firearm that the ammo is intended to be used in.
Good for Federal to offer this service. At $5 per round, I think that's why most of us on here go to the trouble to make our own custom ammo!
