Thread: Hornady Precision Hunter out of 18" 308

Grasshoppa- that's a great result given the shorter barrel length...one would assume Hornady test barrel to be 24" or even 26"??

Yes the Hornady numbers are from a 24in test barrel. You’ll lose approx 150fps with the 18in barrel and gain about 20fps with a suppressor (assuming you’re using one) so velocity will be around 2470fps. Just a rough guesstimate to be fair, as others have said you’ll need to validate with a chrony and actual drops. I’m using the same ammo out of a 19in barrel and I’m hoping for 2500fps
