Have you chronographed your SCAR 17 with that 16" pipe on it? Yer only getting about 2300fps. pretty inefficient. A 7.62x39 makes 2300 fps (granted, less bullet weight).
I've done the testing though... if you can find 308 loaded with 220 gr bullets- you'll be down to around 1900-2000 fps, but your energy is way way up there-still in excess of 2000ft/lb
Forget the 7.62 stuff...You should be boasting about your little spyglass there.
