And that's an 87 gr, you might see a max of 30 fps less at 90 grs.
watch your seating depth, in my barrels they hit lands at 2.219-2.220" (several)
you will want some jump, not into the lands.
I've been doing around 2.180, some guys might seat closer, but just be aware.
I'll check my barrel again, looking back at my notes I measured with a 90gr GMX bullet , I'll check it again with the 90gr ELDX before seating. Unless I got it wrong the
C.O.L. : 2.140 is overall length ? for the when loaded like Hornady . I didn't look up a definition of C.O.L. I assumed that was what it was. and I know the old saying so maybe I shouldn't do that
and yes everything I am doing is for the bolt gun
I know I can't get what Hornady did (every barrel is different)
But
CZ527. check
24" , 1 in 7.5" twist. check
Federal 205. check
Max O.A.L. 2.26 but 90gr eldx is 2.14. check
I'm using different brass either once fired Hornady or starline 6.5 gren and picked their info to see if I can get consistent at that first then move on
Thanks for the input
