Long Distance Tuner Adjustments

[Ccrider]

I started to post this in the ongoing tuner thread but did not want it to get lost in all of the statistical debate that does nothing to help in practical application to the target.

How do those of you shooting 500 yards or more use your tuner to make adjustments during a match. I could not find any threads discussing this. With little time in between targets at a match, limited sighters and the inability to see your bullet holes most of the time, seems like you would have to be really in tune with your gun to be comfortable adjusting the tuner during the match.

By the way, I am not looking for an easy way out and am committed to firing the shots down range to figure this out for myself. At the same time, I have no desire to recreate the wheel if there is an accepted methodology for addressing this.

Paragraph one....amen.
Paragraph two.....most of my shooting is 500 yards and in. But although I have been using tuners for about 15 years I have seldom used them to adjust on the fly, for 2 reasons. I have used the tuners to stay in tune as barrel life diminishes, not to find the load. I have from experience learned how much adjustment is usually required to get back in tune and which direction I need to go. I tune towards a temperature range and load at home in a controlled environment. It works for me. I think it's very easy to think your smarter than you are, so I try to avoid it.
Paragraph three....stick to sentence number one.

I have adjusted my Ezell tuner at 600 and 1,000 yards. First I tested it at 100 yards. I found that I could get one hole groups at one setting, 00 at 2 clicks one way, and 8 at 2 clicks the other way. At 600 we shoot sighters on steel. If I don't like what I see I make a very minor adjustment based on my 100 yard data. We shoot 1,000 yards on electronic targets. If I am getting vertical, I move toward the 00 setting. To keep things easy I put 00, 0, and 8 on my tuner with a sharpie.

Try to look at it as if you were tuning with powder charge. Having a tuner does the same thing, essentially but is much handier and easier to use. Yes, not seeing bullet holes makes it tougher to tune but it has always been that way, tuner or not. Establish good notes first and that'll get ya there most of the time but on those days that it doesn't, pretty much forced to read the groups on the last target and adjust or not based on that.
The targets you've been posting with your rimfire tell me you've got this and you'll do fine but yes, seeing bullet holes and having sighters is a much more certain way than anything else.

First I will say I do not have experience tweaking the tuner for various distances. But I view the mechanics to be similar to tuning with charge weight at distances, in that the degree of positive compensation required for each method depends on the effect of velocity differences on the drop with distance and that is the offset one is striving to achieve. This is associated with dialing in the bullet exit time for a harmonic that is only moving a few thou full swing at the muzzle
