    5.56

    Good stuff. I previously bought my reloads from another well known website, but after getting a bunch with bad brass (out of spec resizing) I started looking for a new supplier. National Cartridge has been 100% perfect! Now my sole trusted source for range ammo.

    Cannot beat the price! I ordered 500 rounds and received them four days later rounds came in a plastic bag and solid box… shot 100rds without any issues. The rounds coming in a bag is representative of the company…no need for elaborate packaging to fit in with the competition…no frills, affordable, and reliable exactly what I needed.

    Great Ammo, Great Cost

    I was really skeptical of this ammo but damn has it delivered. Ordered 1000 rounds and have shot about 600 with no issues. Went back and ordered another 1000 rounds as the QC and QA seem to be really good!

    Company with integrity great Quality Ammo

    Posted by Ian Plummer on Jan 22nd 2025

    I bought 500 rounds of 5.56 and have shot over half of the rounds already. I havent had any issues at all and Im very satisfied with how quick my order arrived. Ammo cycles clean and reliably. Also the customer service has been really good for a smaller company. They made a loyal customer and plan to buy some 9mm next. Trustworthy people that run a good business, you cant go wrong!
