It's a 30 Major...which is a 6.5 Grendel necked up to a 30. I did it using the Grendel case several years ago and continue to build and shoot them. It has been copied and renamed a few times since. Feel free to msg me here for details..but it works and shoots great out of both bolt and gas guns. In fact, the 30 Major name was my idea for it as it makes meets major power factor requirements in an ar15 for uspsa 3 gun competition. ---Mike Ezellwildchild said:Just looking for some info from experienced 30 ARX shooters out there.
How's it shoot and any issues?
