Thanks for the advice about that ammo Brian. I've not tried that type yet. I'll try and get some for testing.
I currently require 2 different types of ammo for my No8's. One shoots well with either T22 or Geco and it was rubbish with the Eley Team; however the second rifle loves the Eley.
My No2MkIV Lithgowis less fussy; but also good with the Eley Team ammo, but generally a couple of points behind the No8.
As our Federation have just reduced the diameter size of targets for small bore military trainers by 50%; the group size is now really critical. The 10 is now 25mm (1") at 50 metres; it was 5cm (2")
