I just aquired a charles era jr registered Vickers and would like to learn more about them. This one has the .303 and 7.62x54R kit. The 54R kit destroys the cases and doesn't run long before a case gets stuck so we had a smith run a reamer and recharger it with a sleeve but never really worked all that great. Figured some one near by has already been through these and maybe even has the gauges to make sure everything is in spec.
