I hope they put it in a mid weight 18" barrel.

Ever think your AR-15 could have as much punch as an 30-06 well now it can.

The .300 OSSM has been put through the testing stage by a major powder manufacturer, and has shown that is it not only out runs .308 but also out runs 30-06! 30-06 with a 150 grain bullet runs 2792 fps, but the .300 OSSM (.300 Olympic Super Short Mag) is running 3040 fps with the same bullet. The proof they say is in the pudding, below is a link to the Data Sheets from the company that tested the .300 OSSM, the same sheets SAMMI is going to use to standardize the cartridge, also a link to some ballistic tests of 30-06 for comparison, you be the judge.

No one wants to see a AR15 in a real .30cal? There must be some hunters out there???

Got a link? I find myself skeptical that an AR15 bolt and buffer system could handle a true .300 maggie that heretofore wouldn't even work in an AR10-sized gun. The bolt thrust would be tremendous, and how fat would those cartridges have to be to feed through the magazine?

Olympic has had WSSM guns for awhile. This cartridge is just a standardized .30 WSSM. They use a special upper with a larger diameter bolt. Yes it will out run .30-06 but only by a little.
