[QUOTE="Joefrazell, post: 1883949, member: 101262"] Looking for thoughts on where to go from here. This test was shot at 410 yards. The load is Adg brass (new) Cci250 225 eldm Rl25 I know rl25 is temp sensitive. So trying to keep that in mind while development continues. Weather was good 45-50 degrees, very slight breeze 2-3 mph Primers started to flatten out at around 73 grains but nothing crazy. 74.6 had just a smudge of ejector mark. No heavy bolt lift. What I don't want to do is have pressure problems when it gets hotter out. Now, once the brass is fire formed I may be able to run it up towards that top node if I ever wanted to. I don't think it's worth worrying about trying to get my velocity higher then the 73.1-73.7 node. I think I'll stay in there. I think 2820-2840 range with this bullet will be great. Not sure what happened to 72.2 unless that case just didn't have the volume? Not sure. Anyone have any input? Am I looking at this right? [/QUOTE]
