[QUOTE="Veteran, post: 2444336, member: 118038"] I use the Chris Long Optimal Barrel Timing Theory which involves the harmonic nodes and how fast they travel in steel vs. the bullet time to exit. Yes using the bullet time to exit feature of QL and looking at that vs. Long's theoretical nodes is another way to get you into the ballpark for finding the sweet spots. Its perhaps analogous to Satterlee, Audette Ladder, and OCW methods too. The theory is all rooted in bbl. harmonics. There are 2 caveats to using this. First it may get you close to a charge weight and velocity that matches the node from Longs work, but I view it as necessary to then begin shooting 3 to 5 shot groups on either side of it, or Audette ladders, or an OCW test on either side of it. Like Satterlee it may provide a good quick starting place to fine tune from. Second caveat is you may need a different set of node charts if you have a Carbon Fiber or Stainless bbl. vs. just carbon steel. Long derived that chart looking at fequency nodes for regular carbon steel I think. Yet a 4th method for load development... [/QUOTE]
