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.
