My opinion is that the answer for you lies somewhere between 41.0 to 42.0 grains. With big jumps from 41.0 to 41.6 to 42.2 you could easily be skipping over the accuracy node altogether. As you saw from the other forum, those guys all use more refined measurements and I think that's wise.

So I would start buy loading nine rounds each of 41.0, 41.2, 41.4., 41.6, 41.8, 42.0

Then do the round robin at one paper with 6 targets. Clean the bore and then repeat at a 2nd target and again at a third target. Then you have 3 targets with the same exact loads to evaluate. At that point you'll know a lot more and leave less to chance. I've had many excellent groups that I couldn't repeat for one reason or another.

Good luck
