I had the Saxby and Palmer Galaxy (or was it Ensign Elite ?), after some issues and it being returned, I went from using the plastic to ali cartridges. With careful pumping of the cartridge, I used Eley Waps in .22, mine was actually quite accurate

I also had a fairly early Orion pistol (HW Orion ?) and again, with careful pumping I was surprised how accurate it was upto about 10 yards using hobby wadcutters

All long since gone, I remember a .22lr type mag fed TAC rifle being talked then quietly dropped with ban looming

I still four boxes of six TAC's I bought in .22 never used
