if the issues are with the reloads, then the reloads are to blame, or the reloader,,

FL sized brass? should work fine, but some are better doing Small Base dies,

if you did the reloading, get , if you don't have, a Wilson, or Dillon etc case gauge, and drop a few of the factory green tips in, and they will like fall right back out when you turn it over,
the reloads should too if they were done correctly,
