The chart below is computed using the same G7 point-mass engine that powers the Long Range Science calculators, using the Federal Gold Medal 175 gr Sierra MatchKing as a reference load for the 308 Winchester. Treat it as a starting point — always true it to your own rifle and chronograph.

Drop and wind are come-up corrections (dial/hold up). Wind is a 10 mph full-value crosswind via lag-time approximation. Values assume a 100 yd zero and standard atmosphere.
These numbers are a factory-load reference, not verified DOPE. Differences in your actual muzzle velocity, barrel length, and local air density shift the solution — especially past 600 yards, and even more once the bullet slows toward the transonic zone. Confirm your true velocity with a chronograph and validate on steel before trusting any chart downrange.
Key Takeaways
- Supersonic to ~1,006 yards — enters the transonic zone there in standard atmosphere; cold or high-altitude air pushes it farther.
- Holds 1,000+ ft·lb to ~620 yards — a common energy threshold for larger game.
- ~3.5 MIL / 12.0 MOA at 500 yards, ~11.7 MIL / 40.1 MOA at 1,000.
- ~3.0 MIL of wind at 1,000 yards in a 10 mph full-value crosswind — wind is your dominant error source at distance.
Frequently Asked Questions
How much does a 308 Winchester drop at 1,000 yards?
With the Federal Gold Medal 175 gr Sierra MatchKing at 2,600 fps and a 100-yard zero, roughly 11.7 MIL (40.1 MOA), about 420 inches, under standard conditions. Your exact drop depends on your true muzzle velocity and air density, so true your data before relying on it at distance.
Is the 308 Winchester supersonic at 1,000 yards?
At 2,600 fps it retains about 1121 fps at 1,000 yards and stays supersonic to roughly 1,006 yards. Colder, higher-altitude air extends that range further; hot low-elevation air shortens it.
Should I use G1 or G7 BC for the 308 Winchester?
Use G7 for modern boat-tail match bullets like this one. The G7 standard projectile matches their shape, so the drag curve tracks reality better across the trajectory. This chart uses a G7 BC of 0.243.
What zero does this 308 Winchester chart assume?
A 100-yard zero with 1.8 inches of sight height. A different zero shifts the whole table — enter your own zero in the Basic Ballistics Calculator to regenerate it for your setup.
