[QUOTE="Highdesertmike, post: 1562460, member: 59540"] As already stated, the velocity spread between 56.6 and 57.2 looks good on paper. It is my understanding, and my method, that in a ladder test, I am looking at the actual target and focusing on the vertical dispersion of the individual loads. This determines / shows at which velocity the bullet is leaving the muzzle in tune with the harmonic node. Groups mean nothing at this point. When you find that flat spot, where 3-4 loads are impacting close to each other on the vertical plane, then pick the middle load and start focusing there. Next step would be to start adjusting you seating depth and start to look at actual group sizes. Of course, always be mindful of pressure signs. [/QUOTE]
