Allant Blue pellets or White Hot pellets for me. Use three pellet practice routines for longer distances. This stuff really leaves your barrel cleaner after several shots and I've yet to have a misfire emptying the gun after a morning or evening hunt.
This is not for the budget-minded, although they aren't expensive to purchase. But it might be in the user's best interest to fire the load and start fresh the next day. That's what I do.
