Going on a Dall Sheep hunt looking for a good scope to put on my 6.5x284 Norma mountain rifle. There are so many great scopes today not sure what to get? I am 55 years old so the eyes are not that great anymore. Don’t believe I need a real high power model. Thinking like a 3x18 I have a Trijicon 5-20x50 on my Tikka 300WSM I could use or the wife’s Trijicon 2.5-12x56.Never heat anyone talk about these do y’all not like them? Was thinking maybe Leupold VX6HD 3-18x 50 or? Willing to spend the money for a great scope if they really are better than my Trijicon. My guide said a shot more than 400 yards is uncommon.
