Welcome to the forum.
You seem to have got off to a good start. Is there a specific piece of information you are seeking?

Thank you for the welcome !
Was wondering if the first shots at 41g were more accurate and if that was all me moving, or if the climb in the 41.3 was the start of the spread Also where about would the next accurate node be, is it like 3% or so Thanks again |

What caliber?
Which bullet? What rifle? Optic? What do you want out of it? This is very important to define....chasing best often leaves folks throwing good money after bad for little to no gain. |

I shoot 140 SMK's with appx the same load in a 260 Rem with sub MOA results out to 800. Looks like you are ready to fine tune
I would go back and reshoot that 41 g load a couple of times because it has the least amount of vertical stringing. The horizontal could be wind or mirage induced Lately I have gotten into the habit of narrowing a load down to two or three nodes that seem promising using a ladder with 5 shot groups then shoot a 15 round group of the two or three best. Then I do a string of 20 increasing the yardage When 3 shots are worthless, 5 get you into the ball park with a bit of luck but 15 or 20 shot groups will give you a pretty good idea of how a load/barrel/gun will perform here is a good post on why 3 and even 5 shot groups are really pretty worthless in determining the precision of a load or gun https://www.ar15.com/forums/ar-15/-/118-279218/?
