Should you feel the desire to celebrate National Ammo Day by purchasing ammunition (in compliance with all applicable laws of course), you might be interested in the special offer SG Ammo has for Blazer Brass ammunition. If you buy 1000 rounds of .45 ACP it is only 26 cents a round, and if you buy boxes of 50 (same ammo) it is only 28 cents a round. Still a good deal but closer to common pricing is the Blazer Brass 9mm at the same site. A 1000 round case is 19 cents a round, and a 50 round box is 20 cents a round.
Either prices are about to drop quite a bit across the board, or SG Ammo picked up the Blazer Brass on a special buy because the .45 especially is quite a bit cheaper than everything else. This is American made FMJ brass selling for less than Russian steel cased* ammunition or even most reloads. As a single point of reference, Lucky Gunner has the same Blazer Brass .45 for an extra $60 a case, and even then it is the third cheapest .45 Lucky Gunner has available.
