Default Re: Load Development: Ladder Test

My wife just pointed out a fantastic point...

My aiming points werent 100% perfectly lined up so iIalso plotted them from bull to bull to illustrate the bore at rest. The line (in red) represents the rifles bore at rest while aiming. The blue line represents the bullets release point during the barrels vibration cycle. Note how at first every other shot was at the top of the cycle and every other shot was at the bottom. This profound difference from shot to shot can only be explained by the lower muzzle velocity, and as the velocity increased the profound 'peaks and valleys' turned into flowing waves that cover 2 or 3 shots at a time until the load hit that 'sweet spot' where the bullets were exiting the muzzle while it was at or near its rest point, then resumed the resonance pattern.

Thanks my dear..
