Things I liked: I really like these H&N Pioneer round balls! This load (and the Air Venturi .45 180 gr. round nose) are my go-to rounds for my Sam Yang 909 Light Hunter. They're uniform in shape, chamber easily, and strike accurately with authority!

Things I would have changed: Nothing.

What others should know: Don't sweat the graphite. It helps lubricate the round and won't hurt your gun.

  • David from USA asked:

    What is the lead hardness of this round ball?

    • Mark from USA:

      The hardness is : 10 Brunell Composition is : 95% lead and 5% tin .

  • Brandon from USA asked:

    What are these made of, are they lead? Also what effect is the graphite lubrication supposed to have?

    • Mark from USA:

      The balls are lead. The graphite is used as a lube in manufacturing. The balls are swaged(hydraulically pressed) not cast. Graphite lubes the pellet/ball dies.

  • Abdullah from USA asked:

    I do like the ammo, but I am concerned about the extra grafite that they contain.You can feel it and see it on your hands when you handle the ammo, and that makes me wonder what it may be doing to my very expensive AirForce Texan .457....hmmm

    • Tyler from USA:

      That's what they use to lubricate the ammo, it will not harm your gun
