The military contract is an interesting subject if you look into it. Basically it is and R&D contract.
I love innovation and forward progress in shooting sports but this one is a bit hard to wrap my head around. The PSI is not a problem but the overall process of managing the components etc is. Reloading, case suppliers, case life, .277?????, etc. We are all enamored with velocity, duh, so the appeal for hunters is definitely there with a short barrel and adding a suppressor. However, if sig holds the patent etc how long would it be before the other manufacturers can be involved? It'll be very interesting to watch this develop over time. I know 1 guy who has one and he seems happy but he doesn't shoot several thousand rounds a year like the rest of us.
