Just a follow up to the info that was previously run for me:

As I have been reading around the forums and comparing information, I decided to test out the Optimum Barrel Time calculator, I found posted at http://www.the-long-family.com/OBT%20tool%20V1.xls
I measured my barrel length as 23.7 inches from the bolt face to the recessed crown. I plugged this info in the calculator and came up with multiple predicted nodes where the harmonics should be optimized on my gun. I used the quick load data that was run for me here, and figured out that 42.1gr was the last predicted node, before I started exceeding chamber pressure. I worked my way up to this load today, and was surprised at the results. I shrunk a 5 shot group to a .333 inch group at 100 yards when I reached 42.1 gr of RL17, which was about half the comparable loads. I was super excited to see the predictions come to life. I'm new to the forum, but I'll try and figure out how to attach a picture as well.
