We couldn't do our usual 2 mile hike due to muddy conditions so we ranged all the targets we could see from stage one and added a set of PRS stages at our high power silhouette line. We ended up with 38 shots for record with no sighters or practice time so it was from a cold bore. There were 22 targets on stage 1 and we had 15 minutes to get all of our shots off. Seems like a long time but this is long range. I finished with 3 minutes to spare. Everyone else on my squad timed out with 1-3 targets remaining. Interestingly it seems that my steady rate single loading beat out their rate going from 10 round mags because they kept forgetting to count their shots and clicking on an empty chamber then having to change mags and re-engage. I had 22 rounds loose on the table beside me and just grabbed one and jammed it in each time I shucked one out. It was the first time out with a modified version of my last load. I did some testing the day before and was getting thumbnail size 3-shot groups at 200yrds. Hey, the gun shoots. For this load I went half a grain over my last charge of Benchmark (I'm now .5gn over book) and switched to a magnum CCI primer from CCI 5.56 primers then seated the bullets a bit deeper to get the forward end of the boat tail just at the shoulder and make chambering easier. Velocities are now 2986 average (gained ~40fps) with a 12fps SD. The SD is a little tall so I'm going to have to do a little more refinement. Maybe try BR CCI primers. In the end I finished with 17 out of 38 which put me mid-pack. As usual I was the only .223 shooter and the rest were shooting mostly 6.5CM, .260Rem, .308win and .300WM. I beat one of each. Conditions were pretty windy at times and my rounds were getting blown off by up to 4ft at 550yrds so as you might expect the vast bulk of my misses were windage misses.
