S400 Breech seal still leaks

[p.sharp]

Thank you but er which collet and seal please?

'Brass barrel shim' & 'o-ring 58' on chambers diagrams.

My brother somehow put them in the wrong way round, which gave 9ftlb with loads of blowback.

As mentioned, this will probably be obvious to hardened 's series' tinkerers.

At one time I think it was UKNeil who made some seals for the transfer port area, using an O ring and a brass ring to stop the seal being drawn through and fired out. Also makes them much easier to place, and to keep in place.

It was me mate, I did hundreds of those for people with the problem of the S400 series eating the transfer port 'O' ring........ It's almost a reverse Dowty seal.
