Headspace question.

[Edward Horton]

Your Enfield passed its military head space check BUT your worried because your civilian commercial American SAAMI cases have a bulge.

This problem started after the British burned Washington DC and has never been totally solved, but do not blame the British Enfield Rifle when shooting American commercial ammunition or cases. Also please notice our American game of Football and Baseball also have different rules and point scoring methods than the British and Commonwealth nations.

What you need to understand is American commercial .303 cases are not made to the heavy duty standards of military cases and this applies to ANY commercial cartridge fired in a military chamber


Below, once fired .303 cases from the same Enfield, guess which case is built to military standards and is over .010 (ten thousandths thicker in the base web area at the bottom of the case.

Below the true story of "The Battle of the Bulge"



The thickness and grade of brass is what controls "The Battle of the Bulge" and it is normal for this to happen with commercial ammunition fired in military chambers. Normally military chambers are larger in diameter than commercial chambers and military cases are made thicker to withstand their larger chambers.

Please post some photos of your fired cases to give us a better idea of what is happening.
