Jim,
A Marlin 39A?? Wow! That is great for a first rifle. Hopefully you still have it. I guess after many thousands of rounds it is broken in and not worn out??

Yeah,no telling what city squirrel may eat. Just like pigeons,ones out in the pastures and field harvested are quite edible but who knows what they consume in the city.

If you have a high powered suppressed air rifle usually in 22 caliber,you may sometimes offer to help a farmer or cattleman rid his area of pigeons/starlings.

Be sure to use nonlead pellets so not to contaminate any feed.

It seems that during squirrel season,none are to be seen but as the season closes and I am out hunting coyotes,the squirrels are all over the place.
