You need a piston! - you've gone and done it have'nt you? The Ox mainspring; for Whiscombe equivalent performance!
In the mid-eighties at Cardiff; FWB sent a Techie who would fit breech seals to 300's, and fire them to test, with no pellet in the breech - Sacriledge! - German Fundamentalism! - yet you need a piston. There's got to be a good story behind this. Your Honda 50cc motorcycle broke down; so..
I think I read there is some guy in Brum with a good stash of parts, so contact the NSRA, as the 300 is the still the mainstay of the Club Rifle slot. I see James Maccari is promising mainsprings for 'em.
