Tuning after testing 22lr

crm617

So, I kind of screwed up. Tested yesterday at the Lupua test center and thought testing should be done without the tuner. My fault for not finding out which was the best way. Of course once there I did find out but to late since I didn't evern bring the tuner with me, not thnking at all. You wait 10 months or more to get in there and make a big mistake, well maybe.

I hope those that know here can help me now. There is a lot of knowledge here and I hope to tap it. That all said I did find a good ammo, center-x 12.12 mm Dmax, 11.73mm height, I'm at least pleased with that. My first thing is I don't have to shoot with the tunner, not a bad lot I found. But I do have a tuner and wonder what my best approach is now. I'm not an expert on tuners, read here as much as I can and understand somewhat the Purdy calculator. I know not everyone likes that approch, I get it.

So your thoughts, suggestions, and how would you approach things now? I would like some detailed steps for anyone thinking that I should put the tuner on and tune.
 
Reading posts from those who have more expertise than I, there is not a consensus. Some think a good lot is a good lot, irregardless of rifle and/or tuner. Others believe lot testing with the tuner on is mandatory. You are where you are, work with that lot and your tuner to find the optimum and roll with it.
 
Sound like you got a decent lot but, ideally, you test with a properly tuned fifle, just like you will shoot it.
Seems, Tonys method works for some, not all.
Post back how long your bbl is and dia. Will get you in the neighborhood.
 
It's not that bad a mistake if it even is a mistake, although I choose to send mine in for testing with the tuner in place and set to whatever worked best for my previous lot. If you are as finicky as some of us, there will be some fine tuning usually of a very, very small nature from lot to lot but, it's still likely to be superior to a bare barrel.
In your case, the next step is to install the tuner and get to the range for tuning. There are some very detailed threads here and elsewhere on how to do it, and read at least a couple of them so you aren't needlessly wasting too much ammo. Mike Ezell has put up some good posts and explains it far better than I do.
Lastly, have fun with it.
 
Seems to me you are where you are and what ifs don't count. Tune it as best you can with what you have and, if you feel it necessary, make another appointment for whenever you can.
 
You seem to lack some clarity in what your purpose was in going to the test center. What did you expect them do for you besides provide the opportunity to buy a case of ammo selected from what lots they had available. Do you think that when you put the tuner back on that the lot that was best at the center will suddenly turn to crap and not be the best lot? If you were at the Ohio facility Shane would have explained exactly what your results indicated, which to me are outstanding for a rifle with no tuner. I have won bunches of important matches with ammo that didn't test that well so if you aren't happy and want to pass it along I will trade you a case of Midas+ for it.
 
For that combo I would expect anywhere in between 135 and 225 in most cases. That being said, I have had 0 be my best tune on a rifle. I would shoot 3 shots each at 5 click increments starting at 100 up to 250 and go from there based on results. Once narrowed down a little shoot a row of single shots on each bull with each of the best 5 groups and look for vertical dispersion. Narrow down and do it again.

There is no magic to it. It’s test and use the results to narrow it down. I would find two settings I think are best and shoot at least 2 cards with each as you would shoot a match. Best scores win the setting.

There will be other recommendations as well. There is no right or wrong answer. You will have to figure out what you think works.

I didn't lack any clearity as to what I expected. What I lacked was not having done my homework on how I should have tested, my fault. I actully don't know if the tuner will or won't change things. That is to be determined yet. As I stated above I don't have to re-install the tuner. Things might just be good without the tuner. They might also be better, why I ask where I should start. I am absolutely happy with the results.

You test at Morengo?

Did you have100% confidence on your tuner setting? I am mean you shot matches and won or did good? if not then what you did is what I would recommend.
12.12 mm bare barrel is really good, you will be able to find a tune that will be even better. I found a lot of CX
that did 12.14mm and was able to get it down to 8.6 mm. outside off a bench,

Don't sweat it you did good!

I don’t think you screwed up - without awesome ammo you can’t reliably find a good tune. So it’s better to test with no tuner than a bad tune. Your results are solid and they can only get better.

I tuned starting at zero clicks out on my Harrell’s and moved out 5 clicks at a time. I did that for a turn and a half. Then I went back to the good groups and tested them again and also -2 clicks and + 2 clicks of those good settings. For the best two groups I tested those five click ranges in single click increments until I had my two best settings. Then I tested my other good ammo at those settings to assure myself the tune was universal and not a lot specific thing. That’s my method. It is neither gospel nor aligned with any big names. What I like about it is i do shoot every good setting a few times to weed out coincidentally good groups, which happen.

I have had some opportunities to tune at truly zero wind conditions (daybreak, foggy, light rain or heavy overcast) and I tend to select based on group size. Other tune based on vertical dispersion alone.

I’m not using a Turbo so my barrel profile is different and starting at zero may be a waste of ammo for you. The more experienced guys here have offered starting ranges I would take full advantage of if I were you.

I have to agree with Lee and David. I'd tested with a dozen lots I was not ultra confident in...outdoors, and knew my tune was between 190 and 210. I sent my rifle to Mesa nekkid, and found a good lot of CtrX (12.44 and 14.34) mostly vertical dispersion. I put the tuner back on, and ended up at 198. It's no longer a good lot...it's an excellent lot.

But, if I ever send it back, it will go with the tuner set at 198 with a box of the current lot for comparison.

You did good.

One more for that. My rifle likes 380-385 for every ammo I have shot with a 40 F temp spread over the last few months

I got a new barrel spun up a few months ago. I haven’t had a decent day to tune yet. If I get a call from Shane today I’ll test without tuner.

I’m headed to Marengo Monday. I’m going to take my rest top with me and test sans tuner. If I find something that will shoot in the 12’s I’ll be estatic. I don’t expect to though. 12mm twenty shot group without a tuner is excellent.
 
So instead of the specific recommendation by the center that sees hundreds of guns, to test with your tuner set at your best tune, “ not for me”.
Some of you guys go out of your way to make it more difficult than it needs to be.
