This mat was generously donated to me by one of the most gracious and humble members on the forums, and no it wasn't JuKk0u. However old smiley himself did join me to partake of the fun and festivities. Here are my first set of groups with my new DMR. All groups were at 100 yards. I was trying out various ammo to gauge results. You can see what ammo created each group thanks to my Windows Paint sorcery. There was one group from 5 rounds of mystery ammo that I had and could not identify so if you recognize this ammo, please do tell. Clearly I need more practice but some ammo definitely out-performed the others. My second set of groups in the next picture were beginning to tighten up slightly as I began to get the hang of prone shooting. This last set of groups was more satisfying than the first but I obviously will need more practice to get where I want to be.
