So hard to decide. For hunting it's my Remington 700 in .270, just an all around good fit for whitetail deer and where I hunt them.
For nostalgia my Winchester 94-22 as I grew up shooting the 94-22's that my dad and grandpa owned.
For accuracy I would go with my Marlin 25mn in .22 magnum. That particular gun just fits me perfectly, ergonomics, trigger pull etc. are all just right for me and really helps me do my part as all of my rifles are more accurate than I am.
