We have just had an explosion of the grey squrrel population in the local woodlands. Now the problem I'm having is that the cartridges I use for pigeon etc don't seem to be knocking the little ******s down. So the question I'm asking is do you good folks out there use different shot for squirrells and also what do you recommend for canada goose? I'm giving up until I can be assured of cleaner kills. Oh and the reason I'm shooting the little grey fellas is that they are pretty much wiping out all my loving planted beech and sweet chestnut trees.
