Hello all, I apologize for the stupid question as I am awful using the search engine tools to find an answer to my question. So I figured I would post here on it. I am looking to eventually take a mile shot using a ruger precision rifle in 6.5 creedmoor. Nothing real fancy, if I have to walk it in or have a lower hit percentage I will but its been just a goal to make a few hits on a mile. I understand the round is capable but under powered for that yardage but I am trying to make due with what I have. I will be taking some precision classes in order to do this and learn to be a better marksman. The ruger precision rifle comes with a 20moa base. I plan on running 147gr eld-m hornady factory ammo with a .697bc and 2695fps. As for optic I was thinking of getting based on budget and overall review the Vortex Viper PST Gen 2 in 5-25x50 ffp mrad. I am trying to figure out if I would have enough adjustment for a mile based on that round, scope and with a 20 moa base. When I did some basic plug ins it seems I would not but I was looking to see if any of you could plug in some info and see if I am wrong or if you think I need a 40 moa base. My second question would be if I went to a 40moa how do I figure out if I could still keep a 100 yard zero or not? Thank you for any help in this. I hope to just read through and gain info from your posts/knowledge and hopefully not have to ask my own questions but man I could not find any concrete stuff myself on it.

Full disclosure, I have not tried this but based on my math you would need more than 20 mils of vertical adjustment to get there. Dont think you'll have it with a 20 moa base. A 40 MOA base works out to about 11.6 mils of adjustment to get to zero. You should be able to do that. If someone has real world experience take it over my math. Real world always trumps theory.
A 30 moa barely gets me there with .5 mil of turret elevation to spare going 150 fps faster. 2 other guys I shoot with use 30 moa bases that similarly barly get enough elevation with dialing. If you want to make a 100% sure you might want to go 40. I can still zero at 100 with my setup.
If you want to find out roughly if you can zero at 100. Take your usable dialable elevation elevation from the total elevation available in the scope. Let's say your scope has 72 moa total travel and when you adjust up till the scope is maxed you get 40 moa with your current 20 moa set up. 72-40= 32 available down travel moa. If you add 20 more moa to your set up you should in theory have 12 moa of down travel to play with for a 100 yard zero. Someone please correct me if I did that wrong.

Thank you both for detailed information I appreciate it. I will def be picking up a 40moa base to make sure I have the adjustment needed!
That I can do although I am sure it wont be easy nor A high hit percentage. Its just something I would like to say I have done and goofed with.
the pst gen 2 only has like 20mil total travel, so you're gonna be SOL trying to do a 30 base, or 20 base and 20 mount.
running a gen 2 razor or other scope with 30ish mil travel you can run a 40moa no problem
i'd look at the athlon ares etr. cheaper. better glass. good reticle. 34moa tube. way more evelation travel. will get you to 1760 with a 20moa, or let you run a 40moa

Yeah I have an Athlon that has been great so far but I can get a discount on vortex. So because the vortex viper has only 20 mil elevation getting a 40 moa base is useless unless I go with a razor correct? And I would definetly use the reticle to aid with holds so would a viper and 20moa be okay in that regards too right?
