Taking a walk around the golf coarse as closed late evening with My Lithgow LA101 17HMR Rifle and Pulsar C50 scope shooting Hornady V-max 17g ammo turned out to be a Grey Squirrel stalking session !
Like this way of pest control more than sitting in a shelter with thermos and a PCP waiting with a feeder. The 17hmr outperforms everything. Cheers buddy!
At about 2.07 into the vid that second squirrel appeared left side of tree low left of the screen but I don't think you spotted him. Great thing about the 17 hmr is they are frangible so a lot safer than 22lr in terms of deflection and ricochet.
