My current go to bullet is the 129sst
25.8 8208XBR, COL 2.276, (don't know fps as my chrono is at a friends last range trip)
20" barrel, No pressure signs, at that COL I am still .003 off the lands and fit perfect in my mags. Did some testing last year on COL with this bullet and my grouping tightened up nicely as I bridged that gap and shortened bullet jump.
XBR is my go to powder for several calibers now. Good stuff,
