I'm thinking of mounting a Vortex Diamondback 4-12 Power X 40 MM on a Tikka T3 6.5 X 55 Swede. Where I hunt, the 4 power would be probably all I would ever use. But, knowing I'll leave the gun to my son, he has talked about Western Hunts in the future. Two questions: (1) Is the Vortex a reputable scope, and (2) what reticle would you recommend. their BDC, or, their standard V-Plex. Any and all suggestions/opinions appreciated. Thanks

Tom
