I am in the middle of my first bolt gun build. I am using a Stevens 200 long action, it will be getting a 25-06 barrel first, maybe share duties with a 7mm mag in the future. That said, I need to pick out a scope and mount. I live in west Texas so I have long ranges to test my skill; is there a potential downside to choosing a 20 MOA base? I dont mind spending money on a good base, but I would hate to have to replace it soon because I picked the wrong one. What bases are the favorites out there.

Thanks for the help
Bill
