7 X 64 BRENNEKE

The following data was developed in a Mannlicher Luxus model rifle with 20 inch barrel. We installed a Leupold 4.5 14X Vari X III scope in EAW mounts. As the velocities show, putting a short barrel on this caliber is really self defeating. I am not sure whether very similar velocities could not have been obtained with a rifle chambered for the 7x57 Mauser. We have two rifles here chambered for the 7x64, both have 20 inch barrels. We are planning to remove the barrel off one of these rifles and replacing it with a 20 inch barrel chambered for the 7x57 Mauser. We will then be able to see if there is any differences in the velocities obtained.

RWS large rifle primers were used in Remington brass. All groups are 3 shot at 100 yards
