Swaffham recovered their early season form to register a bonus point victory against a resurgent Felixstowe side – and now look assured of a finish in the top half of Eastern Counties Two.
The forwards provided three of their five tries, the best of them from Chamberlain and man of the match Tom Murray.
Broadland maintained their Eastern Counties Two promotion push with a 17-0 shut-out of second-placed Mistley.
Dereham's hopes of pushing in to the top three took a set-back when they were thrashed 48-12 at home by Hadleigh. Thetford topped the half-century, beating Lakenham Hewett 50-18.
