Home Forums Hunting & Shooting Ask The Gunwriters New barrel vs a broken in barrel and changes in velocity

I have a 6.5 Creedmoor with a 24” Benchmark barrel that in a little over 3 years has had almost 1600 rounds through it. I recently shot some of the same lot Hornady factory ammo through it as I used when it was new and there was less than 30 fps difference. That is just about what the ES of this ammo is.
