With exception of some 2.5" buckshot loads everything I have on hand is Bismuth or Tungsten Matrix. Some of the Bismuth stuff has Birmingham proof monogram on the boxes with cartridge bases stamped Eley. Most of the stuff is 3" which is assigned to be used in my 9lb Winchester pump gun. The
English also load "duplex" non-tox loads consisting of mix of iron and heaver softer non-tox pellets.
