In my continuing quest to find and record via spreadsheet all 2 7/8" 10ga loading data I have encountered the first steel shot loading data I have seen. The link below will take you to 6 new to me short ten loads, 2 for ITX shot and 4 for steel shot. I will be updating my own 2 7/8" 10ga reloading spreasheet with these loads and will post it up in the near future.
