Scary how little info there is online. I found videos from some hacks shooting 1 MOA groups, but otherwise I've not been able to obtain useful information. I'm looking to see who has used one with good success, and then what increments they usually test.
I know the weight on the Harrells Tuner Brake is lighter, and thus probably requires larger adjustments than many other tuners. but I certainly don't want to go to far and get erratic results, so after I work up a charge and seating depth using my usual methods (with the tuner set/fixed all the way reward), I'm thinking I'll shoot 2 shot "groups" every 2 notches (10 notches per rotation) on my 21" HV barrel, and 2 shots ever 3 notches on my 28" HV barrel, and do that for about 2 full rotations and see what I get. Unless experienced Harrells users have other feedback for me?
