I am with the general opinion, you have bad primers from whatever reason or headspace issues, tend to think PRIMER issues.
I have been using 7828 exclusively in the 300wby 84.5 grns 165 Sierra Game King 215 primers - had a few that dumped 100% in whitetails w/o exiting at about 100yds - load is fine in 2 MKV & a Win70
You need be careful trying to make light loads using slow powders.
