I found a bunch of rusted BB's my son left in a shed and decided to load some shotgun shells with them. I also realized that my powder was over 30 years old so I wasn't going to blindly trust the data. I grabbed a semi auto shotgun and started with loads that barely moved the bolt and worked up to loads that ejected about 2' with .7oz of BB's. I tried the same load with 1 1/8 oz #7 and ejected about 6'. Then I weighed the charge and it was about right for the data. Trust but Verify.
