I think this thread is a complete waste of time !
Hamster you are flogging a dead horse or more correctly a thick Geordie.
Proper Cartridges were available at North Wales Shooting School years ago , but George screwed it up.
He bleats on about running his machines efficiently, but fails to see the point that there are thousands more people shooting clays than there are Game or Pigeon Shooters .
Do the sums George , many , many premier grounds use 15,000+ cartridges a day , some are doing it 3-5 days a week every week , then you have charity and corporate events , before you even get to the weekend warrior many of whom are shooting 200 a day.
Most of us do not give a fig about economy powders, primers or wads , we just want a decent shell that performs reliably but not being led by the nose to the fatcats feeding trough to top up their lifestyle .All the reasons for increasing cartridge prices have just disappeared , oil per barrel price is down ( cheaper plastic and transport fuel) Lead price is down , £ is strenghtening ,worker's salaries have not increased substantially for years , so why the outrageous price increase of cartridges?
An economy cartridge could make a manufacturer very popular.
