How to Zero Your .308 Scope

Ensure that your selected scope is zeroed. Zeroing is the adjustment of your scope so that it’s consistent with the rifle, range, and target that you are planning on.  

Since your ultimate goal is to hit targets accurately, steps to take as a crucial step of zeroing your scope include;

  1. Place the scope and barrel of your rifle in alignment, preferably using a laser bore-sight. Start trying for the bulls-eye at 20 and then 50 yards, by lining up the round view with the inner target circle. Ensure that the results are in agreement with your scope and barrel views. 
  2. Fine-tune your scope for long distances after the 25 to 50 yard zeroing. Point of impact, distance, and load are the factors that you should consider at this point. Zero the distance at 100 yards, and the .308s slug weight when carrying to the shot is your load.Game hunters zero their scopes for 100 yards when hunting with the .308.
  3. Practice a few shots, aiming a bit higher each time you hit the target by around 2 inches. Use these as the exact measurements when determining the adjustments required for a target hit at 100 yards. 
  4. Adjusting zero requires the same support you use for your shooting each time, such as a rifle stand or sandbag. You need to readjust zero when your firing support changes, and especially when working with a .308 rifle. 

Frequently Asked Questions

What is the most reliable range for the .308?

At around 1100 yards, the .308 bullet becomes transonic depending on the load, after being fired from a rifle. The crossing-over stage from supersonic to subsonic causes the round to lose accuracy and stability.

For 1000 yard marksmanship, the .308 is the best caliber for reliable accuracy without diminished stability. 

Which are the recommended scope magnifications for target acquisition with a .308?

Depending on the application, the .308 is effective at scope magnifications of 3X, 4X up to 9X on a variable power sight that large game hunters prefer. Tactical or hunt applications that require precision will see the efficiency with magnifications of 8X to 12X, while other applications will vary.
