I am puzzled. Today Oct/2nd, 9mm - 115 Grain Full Metal Jacket - Blazer Brass – 1000 Rounds is $250 + shipping from Luckey Gunner and price of REMAN 115 gr 9 mm 100 Rounds from Defender Ammunition (online) is $260 + shipping. Is there something I should know? I am new to firearms and trying to learn from folks who are in the know.
