For sure. I shot my first one last week. It worked just like he mentioned. Found three groups that impacted the same poi. They were 47.6, 48 and 48.4. At some point I'd like to load one round up of each charge and see it stays sub at 100. He also mentions brass changes. Somewhere in the reading he took a win, rem and some other piece of brass with different brands of primers and was still able to form a group. I don't know if you've picked a load from previous testing but you can load one round .7% above and below and shoot a group. Two of them will group and one will be outside the group. It'll tell ya if your close.
