Range report from here in California on various lots of .303:

Weapon Bren MkI Semi-Auto from Wise Lite Arms,

Batch 1: POFicon 1967. In a word , Utter Crap !!! Hang fires, case head seperations, ripping the base off of the cartridge. Awful Stuff, avoid at all costs, give it away, pull the bullets and just get rid of it. BAD BAD BAD.

Batch 2: HXP Greek 70's production. Excellent, no problems, ran well. 2 partial base seperations, possibly due to the gas system being open too high. Turned gas down, all seemed fine. 250 rounds, almost all hit the gong at 200meters to the astonishment of the belt feed guys !! If anything the Bren on the tripod is just too accurate. No zone of disbursement.

End of test.
