Wingman. I would say almost certainly you have a bad batch of AR2209. The two 500g lots I've used up were ME M5675 and ME M5583 plus 1lb H4350. None gave any excessive pressure even up to 45gr with the 143 ELD-X and 46gr with the 129 SST.
With 44.6gr AR2209 and the 140gr ELD-M I got the follow this morning:
2772fps
2771fps
2767fps
ES 4.87
SD 2.67
Only fired the 3 shots as the range is only 2 minutes drive from my place and has good solid concrete benches. Might have to contact Kiwi Greg about a Bartlein as I love shooting the Creedmoor because of it's accuracy and the barrel won't last too long.
I've found the 6.5 Creedmoor the easiest cartridge next to the 6 PPC I've ever developed loads for. Been reloading since 1974 and precision loading since 1988 when I bought a unused Remington .222 benchrest rifle with a Hart barrel and Jones Custom Products hand dies etc.
