My dad has an Ithica (or is it Ithagun)16 ga side by side that is about 100-120 years old.
It has some nice etching on it and looks handsome.I took it to a gunsmith here in Atlanta and it was valued at roughly $375.00. However he warned me to not shoot it with todays loads because they could loosen up the gun and over time and just wear it out. I wanted to get a second (or third or fourth) opinion. If this is true, how do I determine what would be an appropriate shell for this gun and where can these be found?
