I've been shooting Lapua Scenars out of my .260 Rem lately as they group well out to 600 yds (at least, thus far). Is anyone using them in PRS competitions that exceed 1000 yds? What feedback do you have? I'm considering these for an upcoming shoot but am torn between the 139 gr Scenars (which are most accurate in my current setup) or 140 gr Berger VLDs (which group decent but have a better BC).
