Is it possible to use a tuner and tune very tight at 50 and open up at longer distances. Doesnt seem logical to me but I have had people tell me that. I figure you benchrest guys know more about tuners than anything. Just trying to tune a NRL22 gun with CCI green tag. It doesnt need benchrest accuracy but it needs to shoot ragged hole at 50 and under an 1" at 100. A lot of guys have their barrels and actions matched to Eley but that stuff is high dollar and Im curious about the tuners. I have a Harrels AR tuner and also a .22 Benchrest tuner. Ive tuned guns with them and it seems to really help. Just curious on the question that I posed?
