Our bullets don't need nodes. Or barrel harmonics/ timing. Load up one bullet at a time to find top end and make sure that there is not too much pressure. Then sight it in. Most cartridges I do this in one g increments. Usually I have 4-5 shots working up to top then 4 more to establish an average vel and confirm that es is good. Then a few more to zero. Then head to longer range to shoot for drops.I usually do 5 sets of 5 charge weights (25) going up in 1/2 grain increments to get a more precise estimate, because I've had some show similar performance within a 1.5-2 grain span, and then increase accuracy as I bumped up another .5-1 grain. Almost like it hit a wall right before the node showed itself.
For your method a full box would be better than a sample.
