Seems he's developed a new and improved method of load development.
Yea sure, I've been in the reloading game since 1977 and think I've seen it all. In the end you shoot, and shoot and shoot until you stumble into a combination of brass, primer, powder, powder charge, bullet and bullet seating depth that consistently shoots one hole groups. Or maybe not...ever!
Lets get started.
1. REFER TO YOUR LOAD MANUAL!!! I SUGGEST YOU USE THE MANUAL FOR THE BULLET YOU ARE SHOOTING. IE. IF YOU ARE SHOOTING A BARNES BULLET USE THE BARNES DATA!!
2. Start with the Max load and reduce it by .2 or .3 grains until you have 10 loaded rounds. (Example: Max load is 45.5 grains for a particular bullet, your rounds should be loaded to 45.2, 44.9, 44.6, 44.3, etc.) set the overall length to the max your detachable magazine will allow or 20-30/1000's off lands.
3. Shoot the 10 rounds from lowest load to highest or until you see pressure signs. Record the velocity for each load. You can see the data in a list but an Excel graph shows it much better.
As seen on the graph, the node is the leveling off of the velocity even though the charge weight is increasing. In this case the node extends from 44 grains to 44.9 grains with 44.4-44.6 grains being the sweet spot.
Loading in this "Sweet Spot" should produce consistent velocity and groups. Next we will look at other powders and nodes. Thanks for reading!
