I`ve just picked up a nice condition 0.22 Mk5 Meteor, it has two small holes just behind the scope ,I can`t tell if they are threaded and I`m wondering what they are for.Can anyone help?

Also the rifle is consistantly doing 8.2 ft/lbs with A A Fields and 8.6 with the lighter Superdomes ,is this about right,I was told theses rifles should be doing 9+ ft/lbs .

Cheers

Kenny
