Once my R700 5R sells, I will buying a Tikka Roughtech in .308. I currently have a Zeiss HD5 3-15x42 with exposed elevation turret that I was planning to use. After spending a lot of time reading here, would it be worth it to sell it and buy the Credo 2.5-15x42? This will be my primary hunting rifle for whitetail in Texas under 300 yards. I've really only had experience with the mid tier level of scopes like the HD5 and a Leupold Mark 4 that's on the R700. Thanks in advance for any insight.
