Thanks for the info, I use a Hoehn tuner on my Turbo also on my CZ, Cooper. I shoot short range compared to you. I have just got into 600yrd shooting and I love it. I just set up a New 6.5-.284 Savage 12F T/R it the same as my .308 Savage 12F T/R I put a 12x42x56 NIGHTFORCE BR with a CH3 Reticle and I like it better then Schmidt Bender. I saw a guy with a type of tuner on a 12F it was like that supertuner does it work at short range bench shooting?

Mike.
