I have a .280 AI that shoots one hole with a 140 grn tsx and RL-19 powder. I want to work up a load for the 150 grn ELD-X and/or Nosler 150 grn ABLR and RL-19 powder. There isn't much published data on this combo. Will someone please run it through Quickload do I can have safe starting points and max load? Thanks in advance for your help!
