I don't want to assume anything but have you tried different seating depths to find the sweet spot for your set-up. It's not NBT but NAB but here's my experience off my SAKOM995 in .300 Win Mag:

(1) 70.5 H4831SC 200 NAB CCI250 @100 yards

(2) 71.0 H4831SC 200 NAB CCI250 @100 yards

(3) 71.5 H4831SC 200 NAB CCI250 @100 yards

(1) Is one of many .010-.020 off the lands is the best group.

(2) and (3) are touching the lands.

My chronograph calls for a min of 10 feet from the muzzle.

Good luck!

Re: Velocity not making sense.

Thanks for the help, guys.
I've already fiddled with seating depths and I think I've found the sweet spot as far as that goes. I'm not sure as to how far off the lands I am, because my digital caliper went on the fritz and I haven't gotten a new one yet.
I think I might just try that Ramshot Hunter powder, because it seems fairly easy to find. Varget isn't too difficult to find out here, but when there's a powder shortage, Varget is the first to disappear!

Also, what about Hodgdon 4831? It's also listed as one of the higher velocity powders for light bullets in .243.

Sierra 70 grain BlitzKings...using Varget, I can get the to 3,300 fps from a 20"barrel (youth rifle)...outstanding accuracy and terminal oomph!

And its not all about bullet weight...bearing surface matters

Re: Velocity not making sense.

While I have the ear of these brilliant LHR members, I have another question- how picky should I be when I sort my brass?

Right now I use fired factory cases, and keep all my brass separated by brand, lot, and number of times fired.
I know all the REALLY hardcore guys will probably just tell me to use Lapua brass, but my money-tree didn't fare too well this year, and Lapua isn't cheap.

Re: Velocity not making sense.

I don't pay any attention to the book, except for starting loads. I load to the rifle and the brass. I don't think I have a rifle that will not go to , or exceed "book max", and that charge varies with the different manufacturers books. They are very conservative with their numbers. I don't have brass issues, primer pockets stay tight, and no, you don't have to worry about blowing anything up. The rifle will take much more pressure than the brass. It will tell you when it's had enough. I would up the powder charge and see what happens. It will tel you when it wants to quit.
I think, therefore I am, conservative.
