jimbob86, do you think a 168-gr. bullet leaving a .308 Win. case then going out the muzzle at 2800 fps can do so with normal, safe 52,000 CUP (62,000 PSI) peak pressures? That fast seems a bit too much to me for 22 or 24 inch barrels.
That was what Speer claimed for a comperessed load of RL15 out of a Rem 700 w/ a 22' barrell ..... Optimistic, probably.
The point remains valid, and even more so using a more realistic MV, though: With a .308WIN time of flight is too long for 500yd shots at game unless the animal is bedded..... and not even then, unless the shooter knows his range, wind dope and trajectory exactly.....
