Tuning and vertical dispersion

[Hi-NV Shooter]

Ahh, I see now! I was looking at the IR50 target only. Agreed 253 looks the best on this one. However, on the IR target the results are flip-flopped.
Concerning to say the least...

I agree, the ir50 groups showed different results. I guess time will tell which setting will be what works best.

Keith, you are absolutely correct. By the time I got to 253 I could barely keep my eyes open (sweat and gnats); hence the re-shoot. I do intend to re-visit 249 and 250.

Lee, I can suss out a new system but I can't turn a photo on it's side

Gerry, making a picture post upright is about as far as my computer tech skills will allow!

Gerry,

You had asked about what to use to tune with and I had said use the most consistent lot to find the setting for your setup or you will never know if you found the best setting. below is a target I recently shot in our monthly club match.
I used CX I got from Lapua as well as 2 other lots to find the setting for this rifle a Match 54 benchmark barrel. the target was shot with Lapua Pistol King, untested just a random brick I bought, it was the first time I used it in a match. a friend who likes to use the ontargets software scored the target and this is what it came out to be. the match target score 250-21X
the 25-shot group size per the computer calculation was .281 that is only .005 difference from the 0.276 I mentioned earlier.
this is why I say use the best you have to tune with, so anything below that will /should shoot to the capability of that lot. you know the standard to look for when tuned with your best lot.
