All this headspace information

The box of 500 empty Winchester cases I bought after I got my first Enfield drove me to the point of excessive compulsive headspace phobia. I personally would not recommend Winchester cases for reloading the .303 British Enfield, and I have been reloading for over 40 years. There is a chance the Winchester .303 cases I purchased are defective, BUT prior to this I NEVER had any problem with Winchester cases in any commercial rifle with a SAAMI chamber.

I’m using Remington cases right now and I have 60 rounds of factory Prvi Partizan to shoot and reload. The Prvi cases are the thickest by .010 than any other manufacture and have a larger base diameter and thicker rims than any American made case.

Beelzebub the New Zealander at the Gunboards told me 5 years ago that the Priv Partizan cases were the best he ever reloaded.

Below a factory loaded Prvi .303 case fired without any o-ring, the headspace was .067 and the cases did not thin or stretch in the web area of the case. (these Prvi cases may be made with Kryptonite)



Use your Winchester cases for fishing weights and switch to a better brand of brass that fits these silly Enfield inch non-SAAMI military chambers.

If you use American made cases keep your pressures below 43,000 CUP.
