Always happy to stimulate discussion.

300 AAC BLACKOUT round was approved by SAAMI on January 17, 2011.

On October 23, 2011, SSG Daniel Horner of the USAMU used 300 AAC Blackout to win his 4th USPSA Multi-Gun National Championship.

Ammo from Washougal River at $175 for 250 rounds.
Yes, more expensive than bulk 5.56. So?

The weapon IS an AR-15 with a different barrel. No price difference there.

If you have an AR-15, you can have a 300 AAC Blackout for the price of a barrel. I just bought mine in fluted stainless steel for $160.00.

No claims from me for a "Do it All".

Never 12g --Really? My Saiga 12 has a solid place in my life.
