codyhuntsaz Report post Posted May 14, 2016 I recently purchased a vortex Viper PST 6 to 24 x 50 rifle scope. This is the first scope with a turret I have ever owned so everything is new to me. I plan on going to the range to sight it in tomorrow. My question is, from watching videos and reading it looks like if I want a 200 yard zero I zero it at 200 yards then take off the windage cap, put the shims in and put the cap back on on zero. That will be a 200 yard zero correct? So my question is if I want to shoot at something that's 300 yards away do I dial the turret to 1 meaning at zero it's 200 yards and if I dial to 1 it should be equal 300 yards? I hope that makes sense. Like I said this is all very new to me. Share this post Link to post Share on other sites
DesertBull Report post Posted May 14, 2016 No In order to use the turrets you need some way of calculating the drop and converting it to whatever style of turret you have. ( Moa or Milrad). The most popular way is a phone app called shooter. You also need to know your muzzle velocity and BC of the bullet you are shooting. Share this post Link to post Share on other sites
ibowhuntaz Report post Posted May 14, 2016 Is your scope MOA or MIL? With your 200 yard zero you will need to know your bullet drop at 300 yards then dial in the proper clicks needed to compensate for the drop. For instance if your drop is 8 inches you will need apx 8 clicks on a MIL type scope to hold dead on at 300 yards. Share this post Link to post Share on other sites

ibowhuntaz Report post Posted May 14, 2016 Ok so you will need to look at a good ballistic program. Get your info regarding bullet drop at all yardages you are interested in. From there you need to know how many clicks are necessary at those yardages. For instance at 100 yds you know that 4 clicks equal 1 inch for MOA, it changes at 200, 300 etc. Once you have these two things you can start to understand how to dial in your scope at different yardages. Or just get something like shooter and it will tell you all you need to know. Up and down is easy, wind at least for me is the hard part. Ron Share this post Link to post Share on other sites
