YES, there are no guarantees he's runnning 63k pressure. Smarter people than me have documented not seeing any pressure signs with certain lots of brass all the way to 70k pressure. It would be my experience that anytime you flirt with 3100 with a 150 in a '06 you are near max. I suppose going even 5-6 loadings with pockets still nice and snug wouldn't even be a "for sure we're safe" but if I had that as a final gauge I'd be ok with it.
