One comment I found was there was double the amount of eddystones mad than the others so any failures would be pronounced although on average just the same.
They were used for a shit ton of magnum calibre conversions right up past 458.
I cant see how the original 303's were any worse than any others until they got to the no4.
And no I wouldn't be trying to hot rod them too much myself in the weaker actions although when I do start with my p14 based model e's I might a little.
Nick Harveys reloading data for the 303-25 suggested 2-3 grains more would be possible in the P14 action

For P14 production

Interesting that double the amount of M1917's were produced than P14's
