Choosing accuracy node

[GSPV]

So the "good side" would be bullet holes #3 and #10, as numbered from top to bottom or left to right? These would be the loads to develop?

Also, do you have any examples of ladders shot @ 600y with the same loads? I'd love to see how the two methods compare visually.

You’ve definitely got the point.

Be in a part of the graph where increasing powder charge creates a lower POI on the target. That’s “the good side”.

Sometimes when you do this, you’ll find a place where the increase in powder charge doesn’t produce any change in vertical. As long as that is in the middle-ish of the good side, it’s a great load.

I’ve admitted to a short range bias. I’m not as good with the mid-to-long range. My work to date has been to do this style of tune, look at chrony numbers for low SD, followed by a traditional ladder to confirm things at the range that I’m going to compete at. Ya gotta take this part with a grain of salt. I just do not have enough experience at 600 to 1,000.

Ok I have read the above at least 3 times. Nothing there looks like the ladders I have shoot. Can someone decipher my ladder at 300 yd in layman's terms? thanksView attachment 1055150

Link, your ladder looks Normal. Generally, going on up in the charge beyond your 31.2 may eventually produce a downward displacement of POI. You have a reasonably wide node to enjoy there. Would take 30.7 to the bank

Time for a 3 shot horizontal test,
I wouldn't be afraid to look at 7-8
I'm in late but how many rounds on this barrel?
