Tx, this is what I have been doing. 3 speeds of eley 1044 1077 and my best shooting lot 1056 speed. old sidewinder did this with 2 lots and he says his rifle never shot better. and I am in the middle of testing an m-12 with 2 speeds and so far it looks promising. start with no weight on the tuner. use a usbr target. make 3 piles of ammo, 1 each speed. shoot a couple of filing shots then at 025 on the tuner shoot 1 round from each speed at bull #1 then set tuner to 50 go to bull #2 and continue in increments of 25 untill 500 on tuner. replace the target with a new one. analyze the target just shot and pick the least verticle setting, the idea is to see if the tuner will shoot without weights. then set the tuner to the best spot, add the 1oz adapter shoot the 3 speeds at #1 bull, add 1/2 oz increments and continue to shoot at bull#2 and so on. it has been my experience that when too much weight has been added the shots will string worse than any group shot without a tuner. from there pick the best or if 2 are the same you will need to test those settings 1 will be the best. and from there I go 10 clicks before and 10 clicks after an 5 clicks before and after again shooting groups. from ther I use my best ammo to try a couple clicks each way. it's worked so far maybe someone has a faster way. I veiw the work prior to putting a tuner on actually tuning the rifle, once the tuner is on it becomes a timing issue. it's best to do this in winds that are favorable to a shooter. always use the same ammo mfg. if you have a cronograph I think it would be even easier.
