While there are a lot of ammunition manufacturers out there, they are not all the same. You find many variances in price, quality and accuracy. Personally, across the board, I have been very pleased with all the ammo I’ve received from Minuteman Munitions.
Not only do they offer good quality training ammo at a fair price, but depending on your needs, they offer some very accurate 223 68gr BTHP Match Ammunition as well. Using the Hornady Match AMP Projectile.
As far as rifle calibers they currently produce, they offer both 223 Remington and 5.56mm NATO in addition to 300 Blackout. They also offer 38 Special, 9mm, 40 S&W and 45 ACP. Also offered are they loadings with Blue Bullets. Which are hard cast lead covered in a high temp polymer.
The next time you need to pick up some ammunition, give Minuteman Munitions a look. Good ammo made by a small company here in the USA.
