What is the correct or good yardage to sight in a DSA SA58 16inch using M80 ammo? Also, would you still use the same yardage with zeroing in a 18 inch SA58 Para using the same ammo? I pretty much just wanting a good all around zero for inside of 300 yrds or maybe even closer in. Zombie type battle zero if you catch my drift.

That more or less gives you your 200 yd battle zero.  |

Quoted: ...sorry but could someone please explain why this is? confused... keeblerelf at 25m, the projectile is still rising. At 200, the projectile has fallen back to the same level it was at the 25m point. Bullets don't travel in a straight line, but rather follow a parabolic arc. For 7.62 NATO, the bullet crosses the same point at 25 m going "up" as it does at 200m "going down". HTH |
