Hi. I just purchased a Tikka T3X TAC A1 in 6.5 CM. I am likely going to pair it with a Vortex PST Gen II 5-25x, defender flip ups, Harris/Larue bipod, and a 38mm high Spuhr mount. I need some advice on deciding between 0 MOA or 20 MOA rings. I live on Long Island where the furthest range is 300 yards, so most of my shooting will occur between 100 and 300 yards. With that said, I would like to take this rifle upstate or out into PA to stretch its legs. Will I have issues at 100 yards with a 20 MOA mount? and approximately how far could I stretch it out with a 0 MOA mount. Thank you, this is a new field of shooting for me!
