[QUOTE="Mike6158, post: 2868037, member: 1039"] I've been running tests on Powder and 150gr Barnes TTSX on my 7mm Rem Mag. The first test was with H1000. The powder test started with .3 grain increments, found a node where with a decent ES, picked one to fine powder test (.1gr increments), picked one from that test, went to seating depth test, and then picked one from those. I wasn't thrilled with what I got from that testing so I went to H4350. Group 4 has a false shot in it. I forgot to disarm the LabRadar before I closed the bolt and the LabRadar trigger I'm using recorded BS. The 2nd round is intriguing but that big fat ES 10-13-9 range at 3,000 fps is a gem. I didn't get anything that good with H1000. Temps on the day I shot were pretty steady at 100 deg F so I'll have to check it later this fall / winter when the temps are a lot cooler down here in TX. 85-90 with no chance of snow. Unless we globally warm down to freezing sometime. [ATTACH type="full" alt="IMR Load Test.jpg"]480956[/ATTACH] [/QUOTE]
