7.92 X 54 vs 7.72 X 54r @ 1000 yards??

Would any of you folks out there know the bullet path's of either or both the Standards 7.92 X 57 and or the 7.62 X 54r, especially at say 1,000 yards? I'm putting a POSP scope on a Yugo Mauser and would like to make up a little tag Kinda like you see and on the Swedish Mausers. I've just spent the better part of 1.5 hours surfing on the net to try to locate the needed info with no luck. I'm hoping perhaps one of you guys have done something similar or know where I can get the info. Any help would be greatly appreciated! I use standard loaded 8 mm military issue style and mostly shoot heavy ball from bolt actions in the Russian style guns, Many Thanks-SDH:surrender:
