Out of curiosity, you wouldn't happen to know (as a rough guesstimate) what the average muzzle velocity is of a standard sniper rifle?

Depends on the caliber but for a 170 grain VN era 3500 ft/sec.

Those figures are for sea-level too. These guys are operating at lots higher altitudes.

3500? Seems a bit steep. Are we talking .308 here?

Hodgdon claims a max of 2565 fps w/ 168 gr Boat tail and a charge of 43 gr. of ball-c w/47,600 copper-units pressure. Always not quite an '06, but close.
