kjtrains:
Welcome to the Forum, and congratulations on acquiring your new work of art. (The R9 is certainly in a league of its own.)
As for the Hornady FTX, while I haven't personally tried it in my R9 yet, there have been other Forum members who have done so with mixed but generally positive results. If that is the ammunition you have on hand, I would lubricate the R9, give the FTX a try, and see how your "pup" likes it.
Please keep us posted, and good luck!
