I am looking to have a 20" 6.5PRC built by Alamo soon, it'll be my whitetail, mule deer, aoudad, antelope rifle. I plan to run my TBAC Ultra 7 on the end hence the shorter barrel. I am torn on glass, I am so used to FFP optics since that's all I have used plinking steel LR the last decade, but is it necessary for this setup? Swaro, Leupold, Vortex, or maybe something else? I like the Vortex Razor HD LHT on paper but I have never looked through one nor have I ever had a custom reticle setup for loads. Thanks for any insight, suggestions, insults.
