I noticed a few popular cartridges missing from h guide, 260 Rem, 6.5 Creedmoor, 6 Creedmoor, 30/06. Is it just a matter of published info, is there criteria, is it just benchrest calibers. I ask only because I am interested in a few of these calibers, I have been able to search out most info but the tables and stats included in the guide are a great source. I dont know enough to write one myself so I am just asking.
