Lloyd, I had a 7.5" 4G Krieger, 30" 6 XC, and the 110's were shooting darn good, Perhaps the Mike Ezel tuner had something to do with it. I know little to nothing about tuners, but I had about 8 numbers that shot with tiny, tiny groups, H4350...all 2's. I fiddled with the tuner very, very little. There must be more to these tuners.
The value of a tuner to me is not making the rifle shoot small. That is a result of good load development. The tuner comes into play as round count rises as an easy way to keep it in tune. I never touch the tuner until I have a load. Then I give it one small bump rt, then one small bump lt. If you have a good load neither of those bumps will improve it. As rounds mount and you feel your tune is not yhere, now go shoot a control group, Then bump your tuner both ways . In a bump or 2 in one direction your group will get worse. Now go the opposite way from your base setting and in 1 to 4 bumps your group will come back to what you want. Some adjust by temp or humidity I have never felt the need here in the NE, I could be missing something , maybe. I have tuners on 3 b3nch rifles and have had for roughly 10 or 12 years. This is what works for me through 20 some barrels.
In both my BRX and a friends Dasher 2900-2940 is where they’re shooting.
