.303 Corrosive/Non-Corrosive Database?

[Alan de Enfield]

The accuracy deterioration using cordite and then NC does seem extreme. It indicates that 'all' LE rifles having fired cordite are now inaccurate, as cordite rounds aren't around any more?

I think that is probably true for the well-used barrels with 'cordite erosion' half way up the barrel, but there are still a good number of 'lightly used' LE's about

By the late 40s I think that Cordite was well on its 'way-out' and MKVIIZ had been introduced. Cordite rounds finally ceased production in the UK in the early 60s.
