Thanks guys for the comments, I have been out to try again. The scope in the picture is new on the rifle so I wanted to see if the old one was contributing to the problem. Worked my way out to 100 and fired 10 shot groups when the wind wasn't howling. I tried CCI Std in Solids and HP and Eley Contact and GECO Semi-auto
The best was the CCI HP 1050fps with 10 shot groups of 2.5" and 2.3" so that's going to be ok to shoot Kerry's match next weekend. The CCI Solids were ok at 2.5" for one group and bigger for the other and the Euro-Trash much worse again.
The trigger is terrible so I might give that a polish up and call it quits. Being between jobs at the moment another firearm is not on the horizon.
