It would be hard to tell if the 2 MOA group is the bullet...or the shooter.Perhaps having such a bad bullet would actually make him better.

This is the 2nd load dev I did.I would agree that bumping up your charge weight more than .1 would give you better results, ie you can see the change and spend less time sending components down range. Also have you replicated that the groups are doing that or was this the first test? I've found that shooing a load one day then going out the next to verify with the same load can have polar opposite results. I'm fairly new to reloading but this is what I've seen and a lot of these guys here have a wealth of knowledge and weather or not you like the constructive points they are giving you seeing as saving money is your goal take the advice you asked for.
I can always be the shooter, but I don't think so. I did feel good that day I shot the 2nd test the one I posted initially. 2" moa was the worst, some were 1.1-1.25. I just felt the groups were about equal between the nodes and was looking for insight and ideas for what if anything I might change.Everyone has their own opinion on load dev. If you do more extensive testing you will find those flat spots or "nodes" you are looking at don't really exist, they are something that show up due to low sample size and variation in velocity. Also notice that where you are looking at is the worst ES, not that 3 shots has any real meaning in that regard either.
Basically my load dev has gone to a powder test to find pressure and then back it off a couple grains and play around there with 5 or 10 shot groups and see what looks the best. Then maybe do some seating depth if I wanna try and help it a bit more but I've started to skip this.
IMO .1gr is to small of a step in your testing and depending on your scale is within the realm of error.
.3 or .5 will show more actual change.
I also agree that 2 MOA is possibly the shooter
If you believe in the flat spots based on these tests what would make you want to go there?This is the 2nd load dev I did.
The first was 43-46.3[max load Hornady book] in .3 grain increments
I found two flat spots at 44.8-45.1 and another at 45.4-45.6 with a jump FPS in between that was in both tests.
I shot three bullets for each of those. That day was Hot and Sunny 85+ and 2nd day was cloudy and 70 F
The FPS for both tests were similar and so were the ES and SD.
I went down to .1 to better find the edges of the nodes
