cheers lads,chiefy mate i was putting air arms through it until i got sick of using umpteen different pellets through different guns,so i went to the club and put over 50 superdomes through and as i put em through the groups got smaller and smaller.i did this with all my 22 springers and now they all love superdomes.the only thing wrong with them is they lose a bit of power downrange compared with the air arms.but still more than enough to down any prey at 45/50yds.just perseverance really to get the rifles used to em,DAZ.
