Anyone able to tell me what the material used in breech seals (in my case Brocock Bantam 22)? Wound buna-N be appropriate?
Breech seal material?

Yes, that is the normal material, 70 duro Buna-N. However, you can use 75 duro Viton, and more than likely have better, more durable results.

Has anyone ever tried a shim, or skinny o-ring behind a breech seal to get it sealing better ?

Seems I've read about using dental floss for that purpose and a thin metal shim could be made. Never done it myself.
