Bulk 5.56 Ammo: Feeding an AR on a Budget

High round count training is where an AR earns its keep, and it is also where small box pricing quietly bleeds you. The 250 count bag fixes the math: fewer packages, lower per round cost, and a single production run feeding your whole session. If your carbine drills are measured in magazines instead of shots, this is your format. One bag in the range bag and one sealed in reserve is the rhythm most volume shooters settle into, reordering whenever the reserve bag gets opened.

55 Grain or 62 Grain for Volume Work

Both weights train equally well, so let your barrel vote. Lighter 55 grain is the traditional high volume pick and typically the better per round value; the 62 grain flies heavier and tends to shine in faster twist barrels. Shoot a bag of each once, keep notes, and reorder the one your groups endorse. Both come off the same Michigan presses with published velocities on their pages, so the comparison is honest before the first shot. Whichever wins, buying it in the 250 count format is what keeps the experiment and everything after it affordable.
