Ok, I'll go first.
When I first made the jump from pistols to long-guns I had a pretty hard time adjusting. I had virtually no experience and had to learn as I went along. I was tryin to sight in a shiny new scope I put on my brand new Remy 700 and couldn't find zero to save my @$$. I was tryin everything that I could think of and my patterm was all over the paper.
An ol' timer who'd apparently been watchin me for a while walks up and hands me a set of hex wrenches. I said thank you and politely asked why he'd handed them to me. "Tighten up your rings" he said, "that oughta bout do it". I asked how he knew and he replied with "son I've been shootn a couple lanes down from you for the better part of an hour and the rattlin in them rings is givin me a headache". I kinda muttered out loud "so that's what's causing me to shoot all over the place".
He said, "young man it's either that or you got yourself one hell of a LAZY EYE"!
We both got a good laugh. He shared a few helpful tips and from then on I've been able to sight in pretty much any rifle with three shots. The whole ordeal made quite an impression on me.
When I got into gun forums I thought the name was a good fit and a reminder to always help people out whenever I could. I designed the avatar afterward. I thought it'd be a funny visual representation of the name.
