Since it is a brand new rifle I would start there. Buy a box of factory ammo, NOT the Hornady Superformance or other makes of hot rounds, and try the gun with that. If you get a sticky bolt, (stop on the first sticky bolt, do not shoot any mopre) take the gun and the FACTORY ammo, plus the empty factory case(s) back to the store you bought it. Do not discuss reloaded ammo behaviour or having ever used reloaded ammo.
If factory ammo shoots fine, use these 20 cases to work up a load using H100V. Produces top velocities in the 180 grain bullets at a much lower pressure.
