I find that the longer the range the heavier bullet you use is a bonus. Shot Long Range for several years and finally switched to using the SMK 190's for ranges beyond the 600yd. line. Did very well with the 190 SMK and even though was told that bullet in 308 would be subsonic at the 1000yd line. Perhaps it was but can say most rounds fired for such matches found their way into the 10 and X ring, enough to make High Master in doing so. Just a suggestion.
