LOTS of humans being shot at 1,000+ yards, with a 10x scope. And you don't think 9x is enough to get to 300 yards?!

People can't shoot accurately at that distance because:
1) they don't know how far 300 yards is/ can't judge distance.
2) they don't know SHYTE about their ballistics.


Seriously, while it may seem like a large step for you, ANY 308, with ANY bullet can handle that, no sweat. What you need to do is work on YOU. Trigger control, and recoil management, so you can see your own impacts to call corrections. To make it almost like cheating, buy a scope with matching turrets and reticle, in FFP. Why ANY company would mix and match.... Simply retarded. Moa/moa, or Mil/Mil in FFP, so your reticle is always the same size relative to the target. BDC crap works ONLY IF: you believe the bullet company SINGLE(ha!) G1 BC value is always right. It matches your launch speed, and your atmosphere never changes.

If you want mag, buy a PA 4-14X44 FFP. Otherwise it really doesn't matter.
I regularly shot to a mile with my 308, using a 15x Weaver; not difficult to see at that distance.
