Dr. Mike I don't know if this is possible in quick load yet but you check and see if your magic touch might find this.

300 PRC Hornady 212gr. ELDX N565 powder. So sorry I got the number incorrect. It is corrected to N565.

David, do you mean N570? Never heard of 590 if that’s the case.

David,

I have the latest update, and it does not list N590. I checked on the VihtaVuori site and don't find that particular powder listed. I suspect that you are asking about another powder. Accordingly, I've done a quick workup with N570 for your perusal.

FWIW, N570 has performed extremely well for me in several larger volume cases. I like it.
