Here at ASYM we strive for the best possible loads no matter what the caliber, application or what our competition is doing. Such is the case with our 5.56 Range Training load. If you’re looking for a better way to train then this is the round for you!

We choose to use the highest quality products to give you the most consistent 5.56 training ammunition that you could possibly get. We start with virgin Lake City brass, this base allows for us to have the most consistency we can get for our Range Training load. From there we utilize premier powders to create a smooth, clean burn that give you the reliability you are looking for in a range load. Our primers are OEM USA made and consistently loaded to a depth that balances safety as well as giving you a constant strike that will ignite the same way every time. Our final and most important component is the projectile. Our projectiles are 55 gr and are hand selected to give you the best possible experience for your training sessions. Combining all of these gives us an extremely consistent, accurate range load that will serve you well.

These are best suited for 1:9” barrel twist rifles due to their lighter nature. If you have a tighter 1:8” or 1:7” ASYM recommends looking into our 68gr 223 Tactical Match OTM. This round will stabilize better in a tighter twist and give you a higher level of accuracy for your exact setup. Please also note that this Range Training is chambered in the 5.56 versus .223.

As always, ASYM maintains a high level of quality control with all of our products. Each round is case gauged as well as visually inspected to ensure that you receive the highest quality product possible. This level of quality control allows us to have industry leading accuracy and precision from our products.
