I have had the opportunity to test the ECOSTRIKE intensively on big game hunts in Europe and Africa as well as on the shooting range. I have been shooting the .30-caliber 150 gr. Version in factory loaded ammunition in .300 Winchester Magnum and .308 Winchester. All in all I have killed approximately 50 animals with the bullet ranging in size from African springbok and European roebuck to blue wildebeest, mountain zebra and large European wild boars. Most of the animals I have killed are in the upper weight range of the animals described. With the .300 my average number of shots per animal is . The average is based on 42 game animals shot from distances from zero to 400 m+ (440 y). I have not experienced any malfunctions in any respect. Usually the bullet exits. I have only recovered one. That was from a blue wildebeest bull shot from the front. The perfectly expanded bullet was lodged under the skin on one of his hind quarters. This bullet leaves no metal fragments around the wound channel and it is therefore perfectly safe to feed the blood-shot pieces and entrails to the dogs or leave it to the eagles.
