As close as I could get with RE26 to 60kpsi with @southernman data.

59g - 2921fps 7fps between highest to lowest- decent extractor stamp
I am unsure if my old chrony is telling me porkies- so need to check with another newer chrony- and buy some new brass- as this stuff is 3 to 5 firings along.
2840 seems alright for 162s in 280 rem?
It sure is a please to shoot suppressed.

Those are some massive velocity spreads, heres hoping the chrony is misbehaving a bit or new brass helps. I'd have thought you would get a bit quicker before getting pressure signs like you are, seems like either funny reading or something else might be amiss
That looks bloody close to the QL prediction...and is 2gn and 50fps less than my AI.
my bottom two pics the extractor marks are excessive aye? and the middle would be ok?
Just the bottom one on my phone looks too hot. Play with seating depth. Then may be try a primer swap from LR to LRM or vice versa?
anyone tried ar2225 in 280 or ai? Need to load for 7mmrm soon, and RL26 is blardy scarce still................
thanks mate- yeah sorta wanna kill 2 birds with 1 powder
if i can
edit- oh i see n560 will do 7mmrm also....
You don't need a 7mmRM if you have a 280AI
N560 works well in both.
