I remember back in the day when my great uncle was telling me how as a child he shot and killed a great big bull moose with an air rifle.
He told me that he was given a Daisy Red Rider when he turned 9 and was out walking around one autumn morning looking for things to shoot at when he come across the biggest rutting moose he had ever saw even up to this day.
He knew that he had only one chance to get it and that it was now or never. So he snuck up close, then he snuck up closer until he could almost poke it with his BB gun. He then took careful aim and let half his breath out and fired into the right lobe.
At the shot, he said the moose started a tremendous thrashing and splashing so he dropped his gun in the mud to duck and cover. He said the ruckus went on for what seemed like an eternity followed by complete calm. He waited an extra minute or two before he braved to look up and was stunned to see that great big moose lying still and limp.
Seeing this, he started to root around in the mud until he was able to retrieve his trusty Red Rider, which he immediately shook clean and recocked. He then approached that moose and just to make sure it was bead gave it another shot at point blank range, but this time into the left lobe. It didn't even twitch, so he knew he got his moose.
I asked him how a BB gun could kill a ton of moose and where exactly did he aim. Did he shoot it behind the ear? He told me that it was all about timing and that he snuck up behind it while it was taking a big drink of water and all he could see where these massive set of clackers hanging down. He then took aim and shot him in the right nut while his head was under water causing it to take a big gulp at the shock and drown itself.
Happy hunting!
