I didn't have the greatest luck with the R50 last month, but I recently grabbed a few bricks of wolf match extra to try out. From my research the wolf, SK and lapua are all just batch tested then categorized/branded by the same manufacturer in Germany. Supposedly the wolf match extra tests slightly better than the match target. Which are the equivalents of SK standard and standard plus. The Lapua tests even better than either and so on. Hopefully it gives me the slight edge I'll need to improve my scores. Maybe we will all get lucky and see temperatures below 100 this month, a little less sweat in my eyes always helps my precision shooting. Good luck gentlemen.
