I have no idea. We haven't even started the testing on it

We have several of our new GNR and Firecat cartridges that are rimless that are designed for the AR-10 but the 257 Firecat is the only one we have had time to work with. Sean has the 376 GNR barrel for testing and we have the data on that but we haven't tried it yet in a rifle. So right now I don't have anything that I know for sure that it will work in his 700.
