For someone to run this for you on Q.L. you will need to give your, Barrel length, COAL, and the Temperature it was when you were shooting.
I will run it for you tomorrow night if you provide the info requested, if someone else doesent help you out first.

Ok I set up my chrony with the 140 Amax, 48.8 H4350 and got 2980 average, one thing I noticed coming from a 6BR is that the primer pockets, some primers are showing a lighter pressure to seat them from a new case, is the 6.5x284 known for primers getting loose in the pockets, I don't feel the load is too hot, a very light resistance is felt on bolt lift after the shot.

QUESTIONS----

you need to tell us all the gory details --- WHAT primers, brass, how many times fired, DID you uniform the primer pockets??????
