I allegedly may/may not have purchased 7.62x51mm ammo from them in the recent/not so recent past. Great prices, and most of all FREE SHIPPING! 500 or 1000 rounds weighs a lot and it's the shipping that kills you on cost.

Click on the link in the blue box for 308/7.62x51 and scroll down to the Dynamit-Noble (GERMAN) - NATO 7.62x51mm 147 GRAIN FMJBT BALL. I can attest that it is great ammo. They also get some from time to time that has slight case corrosion from storage and they sell it bulk in a .50 cal ammo can at around $200/500 rounds. I may/may not have an HK91 that may/may not eat this stuff all day long. I may/may not have 1000 rounds of WOLF too, and while I like their new anti-corrosion olive coating on their shell casings, it is some really dirty ammo. I may/may not have burned through 20 20rnd mags of the Dynamit-Nobel last time I fired it, and my alleged weapon was as dirty as the first 20rnd mag of WOlf FMJ. It is the cheapest I have found, and the best bang for the buck, so to speak. $.50 / round is pretty much normal these days, true knock-down power does not come cheap anymore!!
