These Balle Blondeau bullets herald back to WWII. Frenchman Pierre Blondeau designed this projectile for shotguns for the resistance movement. After the war, this shape fell out of use for more traditional shapes.
The Blondeau-shaped projectiles were rediscovered…and promptly forgotten…several times over the intervening decades until the potential of this slug was realized, again. Today, I bring you the Balle Blondeau .50-caliber airgun bullet, which displays excellent potential for hunting with your air rifles.
