[QUOTE="rgmeddn, post: 2259404, member: 56465"] That's a GREAT group vertical! Sounds like you have the fired brass bump just right. You can verify by adding a layer of scotch tape to the base. See if your bolt flops. That's 0.002" per layer of tape, so ideally only 1 layer should stop the flop.. Best way to find the lands is to keep seating your bullet deeper and deeper until you get bolt flop. Go in steps 0.001" at a time. That's your starting point for finding your best "jump" for that bullet. This starting point will be a BULLET SPECIFIC thing. Save that (empty) round for reference. [/QUOTE]
