Your barrel is still settling in and velocities will continue to be erratic until it stabilizes. Most T3X barrels I’ve shot have settled in right around 60 rounds through it.
Shoot whatever you have and get comfortable with the new rifle. Once you’ve put 50 or 60 rounds through it start seeing which factory ammo works well for you.
