    I was bored and was interested in how we could make heavier pellets with out making them extremely long or actually “bullets” or slugs…. so I found this list of metal densities. Who wants some Platinum pellets!!!!

    Osmium – 22.61 g/cm³
    Iridium – 22.65 g/cm³
    Platinum – 21.45 g/cm³
    Gold – 19.3 g/cm³
    Tungsten – 19.25 g/cm³
    Lead – 11.34 g/cm³
    Mercury – 13.534 g/cm³
    Silver – 10.49 g/cm³

    i tried to also do a comparison of platinum pellets vs lead pellets with cost included, but all the napkin math and conversions quickly overwhelmed my tiny brain🙄  Sorry guys!!!

    Hell, lead pellets are expensive enough!! I would have to sell all but one airgun to afford platinum pellets. Lol.

    You forgot depleted uranium, which is actually economical enough to be used in military as an armor piercing projectile 🙂 It is 70% denser than lead.

    Well AJ, you should first check the DU for a warning label to see if it is known to cause health issues in the state of California.  If it does, just stay out of California when you use it.  Imagine being the first kid on the block with an armor-piercing airgun.

    If I remember correctly iridium is one of the rarest elements.

    Not just the rarity that’s the problem with some of these metals, but also their hardness or lack thereof.

    “JDShapp”Not just the rarity that’s the problem with some of these metals, but also their hardness or lack thereof.

    
However, an alloy of gold and silver can be made to get the hardness to a level that matches the hard lead pellets that we like.

    The thing is, the required twist rate goes down as density goes up.  IMO, most airguns have a twist far faster than is needed for diablo pellets anyway.  A near double the density pellet might start having overturning effects due to spinning too fast. (See Tippe Top video):

    Like the Tippe Top, pellets have a center of mass well in front of the center of geometry.

    No doubt lead is the best metal for our hobby, but we could all be James Bond for a day, “The Man with the Golden Pellet
