129 SST over 2520 Rem 7.5 primer col of 2.32 Howa minni 20" hb four groups of five rounds @ 100 yds
28.5 = 2318 fps
29.0 = 2343 fps
29.5 = 2395 fps
30.0 = 2408 fps max load with slight drag on bolt

Huh.

I've been running 130 ELD. Just finished another round of testing with AA2520 @ 30.4 - 30.9 and in the low 2500s. My node was in there somewhere from previous testing at the same COAL. IIRC I was north of 32gr before sticky bolt, still no ejector marks or cratered primers.

Regardless, the heavier SST seems to do better accuracy wise, or it happens to like your barrel - SST being the only bullet aside from Nosler RDF that has to like the barrel, not the other way around.
