Still, looks like you are on a winner with both of the 40.2 & 42.6 loads but i'd personally stick with the 40.2 as they look most consistent.
Good work. Get them out to 100m and shoot a bunch of groups to confirm.
What is your intended use for the loads? If you really want that extra velocity, i would actually give 42.2 a run as 42 & 42.4 both have a similar POI but 42.8 is high and ever so slightly to the right of the previous loads which may indicate why the 42.6 is displaying a little left to right stringing. It could just be you as the variable but it is hard to tell from 50m groups.
How far off the lands are you loading?

It is the length of the pole that changes the point of momentum that helps steady him. It was shown very often in different ways on the TV show "The science of being stupid".

I think you are missing the point that he quite enjoys the process.
Also, those groups are 50yd. Some of them would be 2" at 100yd.
Nothing wrong with being thorough, especially when you are new to it and learning basic processes for tuning a load.

Huh with all due respect exactly what competition are you talking about here? I ain't no F-class supported shooter, but I grew up shooting fullbore and UIT target these days mainly metallic silhouette, and cheek weld is absolutely paramount in achieving consistent sight alignment.
A lot of Bench Rest guys (depending on class), a lot of F class whether shooting off a rest or bipod F/TR. Have a read over on the oz fclass forum some of the guys or should i say most of the guys over there are the very top F class shooters in Australia currently preparing to go to Canada for the world championships. A quote from over there
"To the point that free recoiling rifle setups can and are being used. There is no forearm grip being used, there is no cheek weld being used, even contact of the
butt with the shoulder is not used. The grip of the rifle by the trigger hand is not always used the trigger is being pulled by a pincer motion of two fingers."
"True. I've ended up shooting FTR totally "Free Recoil" with a specially designed low long stiff rifle using big bullets and a Very light trigger."
