Description
The DoubleTap 223 Rem 55gr FMJ load is built for shooters who want more from their 223 Remington than typical factory ammunition delivers. DoubleTap loads a 55 grain FMJ-BT (full metal jacket boat tail) Match bullet to a rated 3300 feet per second, producing about 1330 foot-pounds of energy from a 22 inch barrel. This 55 grain boat tail load is DoubleTap’s match-grade take on the most popular AR-15 bullet weight, packed 50 rounds to a box for practice and competition.

Many shooters pair a practice load with a heavier match or hunting load. The DoubleTap 223 Rem 55gr FMJ is the lightest option in the lineup, alongside the 62 grain FMJ-BT and the 69 and 77 grain HPBT match loads for longer-range work.
Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance DoubleTap builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the DoubleTap 223 Rem 55gr FMJ until you are comfortable with it, and store the rest in a cool, dry place in the original box.
If you are stocking up, this 223 rem 55 grain fmj load is a practical way to keep one consistent round in your range bag, and doubletap 223 ammo in heavier match weights is available when you want to stretch your shots farther.

Why Choose DoubleTap 223 Rem Ammo
The 55 grain bullet is the classic weight for the 223 Remington and works well in the common 1:9 and 1:7 twist AR-15 barrels. DoubleTap rates this load at 3300 fps and 1330 foot-pounds from a 22 inch barrel, with roughly 3150 fps from a 20 inch and 3000 fps from a 16 inch carbine, so it shoots flat and fast from almost any rifle.
When you compare 223 rem target ammo, consistency is what separates a good practice load from a cheap one. The boat tail bullet holds velocity better at distance, and the 50 round box makes it easy to buy from one lot. Note that this load is labeled for 223 Remington; if your rifle is marked 5.56 NATO it can safely fire 223, but a rifle marked only 223 should not fire 5.56 ammunition.
DoubleTap Ammunition is an American company known for loading popular calibers to their full potential, especially the 10mm Auto and other magnum handgun rounds. Doubletap 223 rem ammo is loaded with quality components and brass cases, and many shooters choose it when they want the performance a caliber was designed for rather than a reduced-power range load.
AR-15 owners, competitive shooters and anyone who trains often with a 223 rifle will find this a dependable practice load. Always confirm your firearm is chambered for 223 Remington, wear eye and ear protection, and follow all federal, state and local laws.
