Fixed power equals less issues. That being said on my 9.3X62 I have a Burris Signature Safari 1.75X5. Bullet proof. Another scope that I trust is a Kahles Helia 2X7X32. Both in a #4 reticle. Unfortunately both are no longer made and only available used.
That 1.75x5 sig safari was one of the best scopes Burris ever made. I have a posilock version on my Ruger African.
