If you look really close even the hole that looks good isn't quite there

Running a Ezell tuner on a 308 F-TR rifle I do things a little differently than the short range guys do. It's pretty much a given what velocity I'm going to shoot and as for jump or lack of, I know from past history what the bullet I shoot likes. I do initial tuner twisting at 100 yards and then move to 300. And yes, if I had longer distances to test I would, but 300 is what I'm limited to. I'm going to post pictures of 3 targets below. All were shot within 10 minutes or so. I moved the tuner 1 mark and then 1/2 of a mark for the last target. Only adjustment to the scope was to put 3 clicks left on after the first shot hit the target on the second target and I wanted to stay in the white. I was shooting in a 10 mph 90 degree crosswind. Which is about as calm as it gets in the panhandle of Texas. I've used several different brands of tuners and they all have worked. I have to say, the Ezell is my favorite so far.
vertical went from 2.5 inches to. 50. I posted this from my phone so if it's a jumbled mess, I'll try to fix it later.
One last thought, the first tuner I had was made by Mike Bryant. He told me something that has stuck with me. " A tuner won't make a bad barrel shoot but it will make a good barrel shoot better "

You can. I start out with the tuner on the rifle.I start with a square mark on the bullet and a given powder charge close to where I wxpect to end up. I start backing out of the lands .003 at a time. When I find a good spot, that repeats, I start going up a tenth at a time until I find a repeatable good spot or hit pressure. If I do not find a good spot I will then go down in po9wder from my starting spot, seldom get to this step but it did happen 2 yrs aho with a button barrel, I normally shoot cut barrels. When I find a spot that will repeat with group in the zeros and ones I get the Lab Radar out and ck ES. I usually can adjust that with primer brand shooting for low single digits. Once I am there now I will try to refine what I have with the tuner, maybe making the hole nice and round.I shoot the same round in 2 rifles done with the same creamer and after about 10 or so years with this combo I have a real good idea were to start. Most of these barrels have shoot the same powder charge with in .3. The one exception was the button barrel. As I pile up rounds over a season I keep in tune strictly with the tuner, I seldom change the load. I have a time or two at about 1500 rounds went .004 arbitrarily deeper in the rifiling then retuned with the tuner only. I have only done this to see if it helped. With one gun a shot for 2.5 seasons about 4500 rounds, still shoot fine. I would retune every month. I guess if I ever had a hummer it was than it barrel. Did not need wind flags with it, hold it in the middle, it went in the middle. I love my Bob Green tuners.

Too much fussing for me. I use the Rifle Accuracy Tuners (RAS) from Bostrom Gunsmithing. Start with them set up a few marks from screwed all the way in. Find a load with the right velocity you want, play with the seating depth a little on maybe the next session at the range. Then tweak that tuner for best results and enjoy shooting.
Simple and workable, no meed to make a big deal out of the thing. RAS - all you need to know.

Sweet! I've always struggled trying to tune for small bullet holes on the paper. Looks like you have it figured out!
Tim, are you saying when you put the tuner on the tune does not change? I would think adding weight has to change the tune as moving the weight to change the frequency of vibrations is how a tuner works. Perhaps you are only tuning without a tuner to explore the limits of the rifle/barrel before putting the tuner on?
Thanks,
Dave.

That’s right a couple things I want to gauge that barrel and I want to best I can establish seating depth
Not saying you don’t have to tune it with the tuner. Just saying for me it’s best to find the seating depth without it
I have not seen the tuner effect the bullet hole shape the way seating depth does

Well gentleman I just joined you tuner guru's might be needing a little help time to time.

So Tim
Lots of good info in this thread. I'm reading into this by the looks of things that you are able to find the best seating depth by a single bullet hole at different increments. I understand tohe concept but have a couple questions. How large is the increment? What point along the powder charge weight do use for the test (max,middle, low end)? And apparently you hav a little stiffer paper or have it mounted to a cardboard backer of some sort to get no tears? Thanks Lonnie

Nice work Stan, keep us posted on your shooting results.

No I’m not finding seating depth by a single hole. But I do examine a single hole to confirm my seating depth testing
I use the Boyer method of finding seating depth
Looks good Stan! I'm not sure we covered some things, as far as just getting started out. Please do give me a call if I can be of help in some way.
Start tuner testing at 100 yards! It's not about final tune at this stage, but about learning the tuner. What you learn here will carry out to any distance. Worry about tune at your distance next!

Thanks for the quick turnaround on the tuner I set up my shank an threaded it to your specific instructions, I hired me a professional to thread this tuner up LOL I will definitely be burning your ear from time to time thanks again.
I though I was talking to a professional!

I can fit that for you in just a little bit.P.S.
I have to sharpen my threading tool first.LOL

I wanted to add a little to what I’ve said about seating depth and the tuners
I shoot group 100-200 yds where a .220 agg over five targets in a yardage is good for 10th place or worse
In other types of shooting a .220 gun can be all you need to win
I have found I need to take the extra step of finding seating depth then add the tuner to the gun
Teen aggs are hard to come by!
