Hello to all. This is my first post. So forgive me in advance of this has been discussed before. I am looking for the advantages or disadvantages from a second focal plane scope. I will be using my scope strictly for deer hunting and not target shooting. I use my rangefinder for all shots on any living animal. I understand it first focal plane‘s are great for arranging targets as the radical stays the same throughout the magnification range. I guess my main question is if I see a deer at 275 Yards and have a 3-15 power scope Can I just range the deer and shoot at 5x. 7x, etc.. and the impact be the same? I am new and will seek some help with wind reading etc... but just wanted to get started on the right foot in regards to scope choice. I was thinking Nightforce SHV or Viper PST since I can get a good deal on one. Honestly I’ll probably never shoot past 400 yards (with lots of practice in the upcoming off season). Thanks all
