Need some advice. I have IMR 4350, RL 19 & 22 & 4828, BR2 primers
Thanks a lotOnly have a older Hornady manual and doesn't have eld-x but has the interbond. Not sure if it's a typo and you meant 7828? If so that's what I would try first with what you have. Be forewarned that the interbond are finicky with seating depth.
I use IMR 4831 or Ramshot hunter with the 139's out of my 280AI
Hope this helps
