It is a Brno ZH in 7x57R/16ga - I've made my start with that one and I still own it - here is my first red deer (spiker) I took with it. It was Aug. the 2nd (forgot the year tho...) and I was calling in roebucks, when I came upon this guy - 7 steps away, he was standing frontal behind a small pine tree, feeding. So his head was up and down when he took a bite, however at a certain moment he noticed me and began to stare at me - atm I knew there was no time left, so I took a blind aim in the pine tree where his chest suppose to be and let one off. Scary - never seen it before no later - looked like rubber doll leaking air - without a hint, still staring at me it slowly, slowly just went down and died...
