Nice going Tony, glad your managing to get some practise in mate, whatever I shoot goes to the ferrets as well, looking forward to the start of the ferreting season. I was using 9.5's with single TBG, but found if you don't headshot pigeons with them, then I was getting a plume of feathers and the pigeon pissing off, I thought I'd give marbles ago as i ran out off bb's, m10 hexnuts also work a treat up to about 10m, they seem to swerve any distance after that
