"Either tuner, will not make bad ammo shoot good."
What does that mean?
1) Does it mean, your bad ammo, with the tuner, can not be made to shoot same as your good stuff, without the tuner?
2) Or does it mean bad ammo, with tuner, can not be made to shoot same as good ammo, with tuner?
3) Or does it mean a tuner just has no effect on bad ammo?
4) Or does it mean you won't be able to see a tuner's effect on large group sizes, but you will on small groups?
5) Does it mean, the effect is not same on different ammo, for example, if your ammo shoots .3 groups the tuner might take them down to .25, but if it shoots .4 groups the tuner can't take them to .33?
I have an idea 1) or 2) is probably what is meant but I'm not sure.
