Most accurate box ammo for my barrel - Berger Hybrid OTM Tactical 6.5 Creedmoor 130 grain Hybrid Tactical Open Tip Match Brass Cased Centerfire Rifle Ammunition

I wanted to build a 6.5 Creedmoor gas gun that I didn’t have to load for. After I finished the build I tested 6 boxes of the highest BC and highest velocity ammo I could find. All boxes shot under .5 MOA while the Berger 130 Hybrid OTM shot consistently .25 MOA groups at 100 yards.
