Ladder interpretation, please

[Alpheus]

I tried some groups from the nodes in my IMR 4895 ladder tests at 100yds. Take a look:

Looks like I overshot the node in the 43gr range, I'd guess 43.5 or 43.4. Definitely going to find that sucker next time.
That 41.4gr group is nice, lets take a closer look.
Calipers zeroed at .309. Hot damn, 0.373MOA!!!

This load will be my short range "plinking" load, so I don't care if the 41gr node is tighter then the 43gr node. Still, that group left me grinning ear to ear.
I'll shot some more confirmation groups, along with a couple at 41.5gr, but man, putting holes in paper never felt so good!

When testing loads, I swear you can tell a good load as if shooting in the dark by the way the gun resonates under recoil. Some loads seem to rattle your teeth loose while others just come back like dead weight. The loads that vibrate will invariably throw wild flyers. The loads that go off like dead weight are the accuracy loads.

Pay attention and you can tell.
