Can't remember the last time I had to extract a loaded round at a match. My least worry in the world with a 284. Split the difference with 260AI. Shot one last couple years. Shooting a 284 now. At midrange You will be the difference. HAVE seen many matches where it is impossible to beat a great shooting 6mm.Many short actions will not extract a loaded heavy long bullet 284 sized round without removing the bolt. If your stock allows that no problem. If you have a tube gun type stock a long action makes life easier.
