Not sure what to buy.

Ok. Just shot 24 h&n piledrivers through the gun. I only set up at 30 yards. Barely any drop compared to the kodiak pellets. Grouped very well, but about an inch right of where the kodiaks shoot. I then shot them both at some solid clay bricks. The kodiak cause surface damage to the brick, but no noticeable cracks. The piledriver however shattered the brick. I tried this on 4 separate bricks. Same results.

Still rrally happy with this gun.

the piledrivers also fit just fine in the stock magazine.
