20" 6.5PRC vs 20" 280ai - factory ammo

[MuleyFever]

I know the 6.5PRC vs 280ai has been done but what if you were going with a 20" barrel in both. If you have shot factory ammo from a 20" 6.5PRC or 280ai please post your velocities.

20” Christensen arms 6.5 PRC 143ELDX factory. Barrel had less than 50 shots 2807fps
I’ve never seen a 20” 280AI. I have a 22” and a 24” but have never shot factory ammo.

6.5prc

I have a 20" 6.5SS mag and a 20" 7rem mag
(As close to your duo as you can get without actually having them ha)

The 7rm recoils noticeably more and the two guns have identical ballistics

6.5ss shoots 135 classics at 2950
7rm shoots 150 eldx at 2950

Browning SPR is a factory 20" 280ai.
