Hello all, T R Robb still makes PTFE piston washers and breach seals for the bigger BSF range if anyone is interested ?. myself and a couple of mates have shot BSF's for a while now and have always had good results using old pellets called Danish black box they call them pallets ? but havn't seen them sold for donkeys years , the Venom baveria shoots nice but no nicer than a standard 55 thats been well used and then re sprung and well lubed.
