For you rifle guys this may not be a big deal, but I am a happy camper with my center-grip XP-100 in 6.5-284 (.288 neck). Some days it just all falls into place and this morning was one of those days. A 4-shot group @ 300 yards yielded a .711 group and a 4-shot group at 600 yards was 1.576. I was using my Siebert Leupold 20x LER scope for these two groups and the groups I shot last Friday @ 100 yards. I will use my 3-12 Burris LER w/BP & Target Knobs for ITRC. From now till ITRC all shooting will be done from the prone position. This mornings shooting was from the bench. Man, can Greg Tannel build a bolt rig!
