New hunting ammunition: 10.3 CAPRA

    It’s unlikely you’ve ever heard of this hunting ammunition before: The 10.3 CAPRA.

    The mission was to develop a modern hunting ammunition for “fox to buffalo“, and according to Capra this is the answer.

    The bullet is lead free and designed to deform in a reliable way and to avoid de-fragmentation at the same time.

    My understanding is that the bullet is a solid copper, but with a hollow tip to ensure a good deformation even on smaller game.

    You can see the data below, as you can see it shoots pretty flat. The trajectory looks a bit like a .233 Rem actually, except it carries almost 4 times the weight versus a 55 gr. bullet.

    4738 Joule at 100 meters is not bad. The GEE, or line of sight, is 187 meters.

    There is more information available, but in German only, here: https://capra.shop/munition.html

    If you have a problem with lead bullets, and need lead free, this might be an option. However I don’t really see a huge market for this new caliber.

    Regardless, the Internet now has some information written in English about the 10.3 CAPRA.

    CAPRA have made a flyer with more details, unfortunately it is available in German only.

    The price for 10 rounds seems to be 65 Swiss or about the same in USD.

    50 bullets, for reloading, is 100 Swiss or 103 USD.

    A similar caliber is the RWS 10,3×68 mm Magnum. Check it out here in TFB’s article.
