[QUOTE="Tumbleweed, post: 854103, member: 9281"] Well, I set up the chronograph this early this morning and fired three rounds of 102 grains. Unfortunately I did not get a reading on any of the shots. I guess I was a little early and did not have enough light. Having to get this done before taking the kids to school put a time crunch on things. 2 shots at 275 yards were .75" apart with the other up slightly making the group 2.25". Not fabulous but I will play a little more witht the 102 load and make sure to get speed readings next time. With a 100 yard zero and input velocity of 3240, shooter called for 2.0MOA at 275 yards. My group center was near perfectly centered with my POA. This tells me that I have to be above 3200fps. [/QUOTE]
