Loading 223 / 5.56 with Berry’s 55 grain FMJ Bullets

For this loading session, I used the Dillon RL-550C 4-station progressive reloading press, a great choice for bulk rifle loading!

The press was setup as follows:

  • Station 1: Sizing/De-Capping (top), Priming (bottom)
  • Station 2: Powder Charge
  • Station 3: Bullet Seat
  • Station 4: Bullet Crimp

The following load components and data were used:

Chronograph Data

I tested the 55 grain FMJ load with a 16″ AR-15, and with a precision bolt-action rifle to see what kind of velocity I would see. Here are the results:

Rifle Average STDEV ES
24″ Bolt-Action 223 2666.4 38.6 96
16″ 223 Wylde AR-15 2452.0 14.3 34

A bit surprising that the AR-15 had a tighter SD and ES compared to the bolt gun! I think I could push the velocities much higher with a more aggressive powder charge.

Shooting Full Auto

One of my favorite things to do is to shoot full auto!

We blasted through quite a few rounds of ammunition during this story, and didn’t have a single issue related to to functioning or performance, and had a lot of fun in the process!

Conclusion

These Berry’s 55 grain FMJ 22 caliber bullets are great for loading and shooting with the AR-15 platform. If you’re loading 223/5.56 or similar cartridges, give them a try!
