| so I'm pretty new into scoped AR shooting a lot of iron sight fun. I'm looking to scope a .308 AR build can someone explain to me the difference between the Vortex PST 4-16 vs. the 6-24 and why one would be better versus the other / why the 4-16 has 10 more MOA of travel adjustment and which would be better for 300-800 yd shooting. |

The big difference would be the zoom capability. I've seen guys use a 3-9 for 800 yd shooting. I prefer to be able to zoom in close to my targets. I've been looking at 4.4-27 Vortex has out. I also looked at a Nightforce 8-32. I'm not sure why the higher powered has 10 less MOA. Try calling & asking them directly. |

The rule (my rule) is... 16" barrel - Vortex HS-T MRAD 4-16x44mm - around $550 18" or longer barrel - Vortex HS-T MRAD 6-24x50mm - around $600 The logic being, if you are building a 16" .308 then you are going for something compact and light weight and the 4-16x44mm is a little lighter than the 6-24x50mm If you are going with an 18" or longer barrel then weight is not so much of an issue so go with the bigger scope for longer range. Here's what the Vortex HS-T 6-24x50mm looks like

It just confuses me on how guys like shooting long distance with such low magnification I didn't know if there was some hidden benefit to it besides a smaller scope size/weight which I don't care about. I would much rather be able to zoom more to the target if thats just the flat out only difference in performance between the two. |
| and I am a little discerned by the less travel adjustment for the higher powered 6-24 vs the 4-16 I just want to make just Ill have enough adjustment on the scope to shoot whatever distance that may come up. I have heard needing a lot of adjustment for the .308 round i just ordered a bulk pack of 168g winchester rounds which seemed like good target practice loads |

Heat mirage can be a problem with long distance shooting and high zoom. You can't always utilize past 10x to 15x zoom depending on conditions. I'd personally would rather have more zoom and not need it than not enough zoom. |

I have heard needing a lot of adjustment for the .308 round i just ordered a bulk pack of 168g winchester rounds which seemed like good target practice loads You can also get a mount with 10 or 20 moa built in. This will move the reticle up 10 or 20 moa depending on the mount so it's not center in the reticle at zero but really isn't a problem. Since the zero gets move up 10 or 20 moa then you get an extra 10 or 20 moa of elevation adjustment. Hope this makes sense. |

Hope this makes sense. and 20 MOA in the mount shouldn't too much so that the vision thru the vortex looks tunneled right? |

So it not quite in the center allowing for an extra 20 moa elevation adjustment. Has nothing to do with tunnel vision. High zoom optics attribute to tunnel vision on certain scopes. |
| Im actually looking into the same two scopes now, and going with the 4-16. Take into account your field of view at full zoom, weight, clarity at full zoom, and price. I want to shoot 600-800 yards, and all of this taken into account got me to the 4-16. hope this helps! |

Pst 4x16 has approx 76 moa total adjustment. So about 38 moa of elevation adjustment.
For a 308...Depending on ballistic coeffecient, Velocity (depending on barrel length), Altitude, Pressure.....it will take about 28 moa of adjustment to get you out to 800 yards. It will take approx 35 moa to reach 900 yards....so that will be your approx max range with a vortex pst 4x16 with a normal scope mount. Make sure you buy a good one piece mount like larue, bobro, adm, aadmount. Aero precision makes a good value mount. If want further than 900 yards get a 20 moa base like aadmount. It will take less than 28 moa the higher altitude from sea level. It will take less than 28 moa the higher ballistic coefficient (bc) than .409... higher weight grain bullets like 168 smk will have a higher bc....think match and target bulets... for hunting bullets you may need more than 28 moa to reach 800... assuming the bc is lower than .409 g1 bc. You would have to research it. The shorter the barrel will also require possibly more than 28 moa adjustment. |

I would recommend getting a free ballistic app called strelok assuming you have a smartphone. Then you can put the load you are shooting and have your vortex pst preprogrammed. It will give hold overs and dope for distance you are shooting. If you know the target distance and approx wind speed you will get 1st shot hits in many cases. It will tell you how much elevation and wind to dial into scope. .makes shooting so much easier.
Winchester 168 grain is probably not going to have as high as bc as 168 smk... That stands for sierra match king bullet. Usually for hand loaders. Blackhills ammo is the only factory ammo that has a smk bullet |

Quoted: Watch this. Explains the 20 moa base.  http://youtu.be/Ppuzt3xv4GoI would recommend aadmount 20 moa mount. Thanks for that link. |
