Just wondering if someone could post some load data for how far their .308 can stay supersonic. I know the usual is about 1100, but does anyone have load data to show supersonic speeds past 1300 or 1400 (under I assume near perfect conditions).
This is DOPE from my 17" .308 1:10 Krieger firing a 208 amax @ 2500
Goes subsonic at 1200+, I've seen guys pushing the 208 up to 2700 out of their long barrel 308, that would put supersonic flight out to 1400 at sea level.
I am just starting out to LR shooting and don't know very much. So far my rifle and I have only been up to 400 yards. I'm wanting to see what rounds are capable of staying supersonic at those distances, and because I don't reload or know how, I was hoping someone on here could provide some data.
That, and a few people I know don't believe it can stay supersonic out to 1350 or 1400, so I'm trying to give them proof it can.
