Federal Lake City M855 5.56 x 45 mm 62 Grain Steel Core - 300 Rounds
They also have Federal Lake City M193 for $152.95 w/free shipping in a 500 round case of 20 round boxes. That's less than $0.31/round delivered. --- Now Out of Stock on the M193 ---
Located in Minnesota, so no sales tax anywhere else I assume.
First-timer, be gentle.
P.S.: M855 has the SS109 steel penetrator projectile, so don't plan to use this at any indoor ranges. M193 is fine for indoor ranges.
