Range Report Hornady SST 6.5 Grendel 123 GR barrel length

[Red_Celtic_303]

I have started researching to build a 6.5 Grendel and am trying to decide on barrel length. I’ve been all over the Hornady website and other resources looking for the barrel length that they used to obtain their ballistics data (muzzle velocity mainly) and have been unable to find anything regarding that. If anyone has any tables with muzzle velocities for different barrel lengths, that would be greatly appreciated!

Factory velocities are often generated using a 24" barrel.

I'm getting 2560 loading 28.5 grains of 8208xbr out of a 20" bca barrel. Sub moa shooter that's a hot load so if work up safely
