what's the barrel length for your bolt action?
Also, think about the max distance you want to get down to and the opening velocity.
These are variables but we wouldn't know them of course.
I have read (have not tested however) that the powder "twins" AA2230 and Xterminator - the more modern cans, one was modified for more temp stability and the other was for... don't know -- MV?
Anyway that might be a possibility, not as much MV loss.
Also if case fill allows for Tac might you have a tad left of case capacity, to bump up the load in November?
Finally, maybe your node is wide enough that cooler and a bit slower is still POA and acceptable accuracy...
JMHO.
O, one more thing, sometimes in the bolt actions you can load a bit longer OAL which gives you more powder room.
GRT doesn't seem to "like" the 80 GMX... very high engraving force and can't get up to 31.5 grs even at 2.290.
Now it's just a model...
have you done some ladders with the CX?
Barnes has an 80 gr ttsx.
Maybe CBB bullets.
