[QUOTE="LongWalker, post: 2265113, member: 97337"] Took a rifle I'm going to be using in a couple weeks to check zero and reconfirm DOPE out to 300. Load is 30-06 running a Berger 180 EH in front of VV-N550 in Lapua brass at 2851 avg fps. Reader's digest version is the temp was in the upper 80s and it was walking at 100 for zero and then would do the 2 rounds in 1 round out group. The node is at the higher end and when I put the chrono on it velocities were 10-21 fps over average. I think the hotter loads we're enough to put it outside the node. Load development was done in the spring so it hit the 70s a couple times but not 80 degrees or above. Load was sub-moa out to 500 verified twice before so temperature sensitivity out of the node is the only explanation I could come up with. And yes I triple checked scope, rings, etc. Anyone else ever have a similar experience? [/QUOTE]
