I paid the membership fee today so I could check out the site below in more detail. There are thousands of loads for hundreds of cartridges. The coolest parts I think are the ability to do side by side comparisons and the re barrel/ re bore calculator. There are also loads and actual ballistics for wildcats that I couldn't find anywhere else (unfortunately I cannot justify a 22-30/30 AI now). I could compare that, 220 Swift and 22-250 against each other at the same time for case capacity, velocity, muzzle energy etc. I think it's worth the $19.00 a year. You can check it out for free but you can't see the powder capacities and some of the other tools are blocked.
