The 5.56 Training Pair

55 grain is the standard AR diet and the better per round price. The 62gr FMJBT steps up bullet weight: 2,850 FPS from a 16" barrel, Hornady projectiles, not steel core. It shoots MOA from quality barrels with a 1:7 to 1:9 twist. Both are remanufactured on high quality trimmed brass with CCI primers and 100% inspected.

When 5.56 Needs to Do More

Short barrels bleed velocity, and velocity is what makes 5.56 work. The 55gr VMAX restores fragmentation down to 10" barrels. The 75gr HPBT compensates with mass: MK262 class impact energy, sub MOA at 400+ yards. Perfect for 3 Gun majors, spinner targets, and defensive SBRs.

Is this real 5.56 or .223?

Both. The loads are labeled .223 Remington/5.56mm and are safe in either chamber spec plus .223 Wylde.

Is the 62 grain load steel core?

No. The projectile is a Hornady FMJBT, not steel core, so it is fine at ranges that run magnets.
