Since I have had and used a drilling for about 50 years I will give my opinion.
A fancy drilling with many 'toys' is what we want however its not really needed to get something and to be ready for it.
A simple two barrel combo gun would do it.
Having a .22 lr insert really complicates things and to worry about if a shotgun barrel is 'regulated' with solids is beyond need.
A shot gun barrel loaded with shot will bag about anything and a rifle barrel will reach the rest.
Now we all want more but I have extra scopes for the drilling and I don't carry them.
To each his own.
