The R is inconsequential. As far as the best stuff there: If the Romanian is the Hotshot stuff, its pretty darn good. Bulgarian (if the brasscased) is stupid awesome, as the brass does not have laquer on it to gum up after repeated shots and is accurate for milsurp. I would probably go for the Bulgy as it is probably the best of all the aforementioned. I have never like Czech anything, silvertip also.
