300BlkTalk

There is just so much misinformation that I can only shake my head. Alot of the posters indicate 300 ammo costing three times as much as the 7.62x39. One refers to the 300 as being more expensive and then lists the accuracy potential of the Winchester 7.62x39 WB ammo (along with Tula) after talking about the cost difference. Bad news the 7.62x39 WWB is about $6 more a box over the 300 UMC.

As to the 7.62x39 being more powerful; maybe marginally so at the muzzle but the 300 has much better bullets which will over take the .311's very quickly and continue to out perform them.

Availablilty of course goes to the cartridge that has had more than a sixty year headstart. That said as long as I have 5.56 brass and .308 bullets I will have 300 AAC ammo.

If the 7.62x39 truly did perform out of the AR platform then I firmly believe there would not be a 300 AAC. Tons of AR companies would have been making them by the thousands to fill the demands of their customers who wanted a cheap available .30 cal solution, but they didn't which is a pretty good indicator.

The cheap surplus steal cased blasting ammo is the only real advantage I see over the BLK. The blk has a better bullet selection. (as I posted over on barfcom) The 7.62x39 may be able to be loaded to higher FPS for close work.
