Tuning at 100 yards

[Mysticprecision]

LotC is still your best option. tuner setting for 1.4, 2.2 and 3.4 is where you need to spend more time. 2.2 and 3.4 seem to be best if they aren't the same setting.

Seems you have a consistent right to left wind direction for your range.

Tuner is heavy enough but adding more weight may be helpful for changes due to temp.

There is plenty of info to form decision ... trust the target and score it based on what it tells you. There is nothing more to learn except wind drift and how many other surprises will show up in the lot. It is all shooting very well... despite the occasional flyer. and yes, they are flyers... no more, no less.

Now you understand why 100yds IS the distance to test ammo/rifle IF the goal is longer distance shooting. If you have it, retest the tuner settings mentioned and lot C at 150 to 200yds. If you think things are easier to see at 100yds, 200yds will have flashing lights and sirens.

Today I tried a different rifle with a very similar but different tuner. The barrel is again 26" but it is slightly less heavy at 0.910" in diameter.

I used different Midas ammo, two lots made in 2023. The 2024 lots A,B, and C are not very consistent. Inconsistent ammo makes finding a good tuner setting more difficult.

FWIW, I've tested the five lots of 2024-produced Lapua Midas that are now available in Canada. If anyone wants to know what to expect, I can share some information.

Some groups that were produced with a tuner appear to reflect a promising tuner setting. It was used with the best groups seen below. But not all of it's groups were nearly as good.

Again the tuner setting is not shown, only whether a tuner was used.

And that's all I seen in this post. Slapping on a tuner, shooting a random group on a random setting and saying be the judge, or what can the determination be? So inconclusive results and not a fair test of the tuner. I can slap a supercharger on my Corolla, but without doing any tuning I enter down the road for failure.

I don’t really see anything random about the testing. Shooting a random group?? If all you can see is Slapping on a tuner,Shooting random groups with random settings then maybe this is above your paygrade(which is 4X your wife’s). I’m smelling sour grapes because the OP posted ten targets all under 1/2” and your entry was denied because you didn’t follow the rules. Try to keep the spelling and grammar in check when you submit your rant. Jealousy will consume you.

you can hold onto a grudge longer than a wiener in-between your butt cheeks.

Of course I agree. We can't see anything random about the testing because the OP has not disclosed sufficient detail of the methodology to form that or any other conclusion.

You’re confusing me with someone who actually cares about your opinion! They’re like ask wholes, everyone has one!

Yesterday I showed results obtained with a second rifle and tuner. As noted in post #22 above, one setting in particular seemed to show promise. The groups with this setting (see post #22) include 1.3, 1.4, 2.2, 2.3, 2.4, and 4.3.

This morning I shot more groups with the tuner at that same setting with the same lot of Midas 333 used on yesterday's first three targets.

I've included the ten-shot MV spread, as well as for reference the MV of certain rounds. It was quite calm when I shot the first two targets which comprised seven groups. All the results shown below were with the same tuner setting as those referred to above.

It can be seen that the POI of some shots were not consistent with their MVs.



The range began to get breezes by the time I got to Target 3 so it was the last. It shows the effect of wind as well as POI caused by other factors.

Did you happen to be making sight adjustments on the sighter target on target one? If not would this possibly be caused by barrel temperature? Without the vertical dispersion that group would be very tight.

Sick burn, you stay up past Jepoardy to come up with that one?

I think you're the one that is jelous, as you keep bringing me up, and I consume a spot in your life. Above my pay grade? I'm 40 and only got 9 years left to pay off my house, then I'll have enough to buy a Anschutz every month. Oh yeah and I'm retired. Hardly jelous of you.

JEALOUS is the proper spelling. The only spot in my life concerning you, gets flushed every morning!!

Who has 2 thumbs and don't care? Me..

Is that before or after you poop your tighty whities? Needless, I'm honoured that you think about me daily.

But if you refuse to ignore me, any further conversations will be considered harassment by CGN rules. So last I'll entertain you. Good bye.

Glenn sorry I derailed your thread.

I don't make scope adjustments while shooting a particular bull. I make adjustments in between groups. Sometimes there are hard to detect air movements that push groups from one side of the bull to the other, but since the shooting is not for score I don't worry about that.

The sighter group is most likely a random result. After shooting over fifteen bricks of ten-shot groups this season, I think I've seen all kinds of patterns in the groups that are produced, some even beginning to look like letters of the alphabet.

I don't think barrel temperature played a role. The temperature outside was about 10 - 11 degrees Celsius when the group was shot and only the fouling shots preceded it. The temperature of the barrel would remain fairly constant. The rate of shooting is no faster than about one round every 30 seconds.

Sorry if I've missed it but could you tell us what you have up for wind flags.

 

[Longstud]

I’m assuming you begin each session with a clean barrel. Do you clean while shooting, between targets or at a certain round count? Thanks

 

[grauhanen]

Sorry if I've missed it but could you tell us what you have up for wind flags.

I use wind flags that were purchased as rimfire-specific range flags. I don't claim to be skilled at reading wind flags effectively. As readers may understand, they are often tough to use reliably and effectively at 50 yards. At 100 yards the effective use of wind flags is tougher still. As distance grows, it takes tremendous ability to account for wind.

I use my wind flags to confirm that calm conditions continue. When they don't I know to expect that to influence results. I don't shoot when it's windy as this can produce results that are not reliable.

The last week-and-a-half in my area has had remarkably calm mornings. I try to take advantage of that. Of course wind flags don't always reveal all air movement, especially at 100 yards. Even during otherwise windless mornings, air movement can be caused by uneven warming as the sun rises and warms up the air and ground differently and unevenly across the range. I observed this often over the past twelve mornings I was at the range.

I begin with a clean barrel and I always shoot foulers before shooting seriously. I shoot SK ammo as foulers before shooting Lapua as they both use the same lubrication.

For several years my practice has been to shoot two boxes (100 rounds) before cleaning with patches with Rimfire Blend followed by dry patches. I clean my barrel after each session and use a rimfire bronze brush for two - three passes.

Cleaning regularly ensures that accuracy isn't compromised. It also prevents the development of carbon rings. I haven't seen one in years -- and I don't use carbon remover (although I do have some that I got years ago). Of course others may use different methods and have no problems either.

No. SGF.

I use FMT. With a good wind meter different lengths react differently at different wind speeds. With time its fairly easy to work it out. I use ball bearing fishing swivels to attatch onto bent metal rods with loops on the ends.

FMT? Please explain.
