The first rifle I shot was my brothers it was a Sears bolt action .22 single shot. This was the gun I took my first squirrel with.
My first gun was a Marlin 60, this gun thinned out the critters in the local woods very well.
My 2nd rifle was a Polish M44 and with that gun I was hooked on mil-surp rifles I have bought (I call it investing)about 50 or so since then.
A Marlin Model 100 single shot .22. Still have it one of these days I would like to get it restored.
A Lee Enfield was my second and all time favorite from my childhood.
