[QUOTE="jrock, post: 1984351, member: 78569"] In a time crunch, I like to do at least the following. Start at a 20 thou jump. Do a pressure workup test. I'd suggest .5 grains with the Magneto attached shooting at the same target with the same POA. Find max and the "safe max". You should see how the rounds group relative to the powder increments (at 100 yards). For range day two, load 3 rounds at 0.3 grain increments several above and below the safe max. Shoot for best groups at 100 yards. Pick the best one and call it a day. I say this gets most of my guns shooting to 75% of their potential or better. A third range day would be required to get drop data to confirm velocity. [/QUOTE]
