Once again..for clarity..I'll get to it Timmy. Maybe tomorrow, maybe the next. Follow along quietly or f off. Clear enough?You, again, quote my post without answering the very simple question. If you have an answer great, if not start a thread on tuning perhaps.
I asked you a simple question a couple years back……still unanswered, because you simply don’t know,
Tim, I've never seen any major difference other than a click or 2. But then I'm apt to do that any given Sunday so....OK, since this tuner thread has bumped back currently, I have a question.
For those with guns tuned with ELEY, what, if any, adjustments made for Lapua ? Seems like some don’t readjust…..many/most seem to.

Is that what you've found?
I have’nt found anything yet, this spring we’ll see, so for now,we get a comedy in two ( or three) acts.
Oh, I forgot, tune for lot changes???? More insight from a non- participant.
Never heard of them making any tuner adjustments. They may, I don't know.
Let's cover one thing at a time and why being very methodical matters greatly. We'll start with a pic of a test target. You can clearly see group shape, size and poi changes.
For now, let's address poi. You can see a very clear sine wave on the target and a sweet spot very near both top and bottom of the sine wave, which is physically barrel swing. More later...
Without detailing what that image represents it doesn't tell me much of anything.
Do you care to elaborate at all on how that sequence is shot?
Sure. Those are 3 shot groups moving the tuner only 1 mark at a time. Fwiw, each mark is .001" of tuner travel.
I'll explain more later.
Yes, there's always "later" isn't there?
When you finished a three shot group and turned the tuner did you shoot the first shot of the next group or did you shoot one off-paper?
Take a good look at that image folks, the one with the groups......the one that says "Panda" as in CFBR.
That's because Mikey is on record that RF and CF barrels act EXACTLY the same.
When that there was first opined, I received multiple PM's across a couple forums, from some very, very accomplished RFBR guys, including names everyone would know and respect, calling bulls..t.
Now to his credit, Mike employs some good methodology regarding tuning discipline that is far better than some random crap some guys utilize, however having a rather pedantic style with zero creds in the rimfire world........well you decide.
Well, i stand corrected.
When time permits please tell the class why, in a thread about rimfire tuning, you post a target with 6mm three shot groups.

Mike, any idea why we sometimes induce horizontal into the group when moving a tuner? I figured it was due to the bore of the tuner not being concentric with the bore. I saw it somewhat drastically once on a barrel that the tuner didn't fit real well on i.e., too loose. As I recall it had about .010 runout. My "cure" for it was to bore the tuner out when it was on the barrel in the lathe. Seemed to work .
Anyhow, Interested in your thoughts on it.

I am not Mike, but just to confirm my observations, my Aussie tuner http://www.loweyproducts.com/products.html was specifically bored to suit my barrel dimensions and with a 'locator' stop fitting so results are repeatable.
I visited my local range today. Vertical error was zero, just like when I tuned it 3 days ago for 'one holers'. Wind was about 10 km/h left - right.
Horizontal drift was present, my wind flags confirmed that a tuner cannot compensate for wind so made a mental note 'Watch the bloody flags' as I had a horizontal spread of about 0.3 in, my fault.

I've never noticed that drastic with rf. I'm going to have to pay more attention I guess. Its my understanding that its best to be tuned at the top of the wave opposed to the bottom.

You also cannot ideally tune in a 10km/h wind.
One of the single biggest mistakes shooters make is trying to tune in condition as opposed to waiting for condition to get as good as possible at your range.
