In the 1970s the American Rifleman Magazine did a long article on warped banana shaped cases fired in the M14 rifle. The culprit was small base diameter cases and uneven case wall thickness, this caused the off center case to expand more on one side when fired and when resized the cases warped and pushed the base of the case off center with the bore of the rifle.

The American Rifleman Magazine didn't blame the M14 rifle for having a losey goosey bolt. The fault lay with the cartridge case and its manufacturing methods.

Below you can see how the larger base diameter Prvi Partizan cartridge case and thicker case walls can "PREVENT" a warped banana shaped case. The Prvi Partizan cases have a larger base diameter and thicker case walls compared to the Greek HXP case which were fired in the "SAME" Enfield Rifle.



The losey goosey No.4 bolt head below was caused by bolt thrust wear on the mating surfaces between the bolt body and bolt head. Please remember to remove all oil and grease from your chamber before firing your *Enfield rifle.
