I would go with the 32-20, because it is a 32-20!

I have a Turnbull 92 deluxe takedown, had it for over 20 years. I have never been able to get the rifle to come apart. I don't worry about it too much. Other than transport, not a lot of reasons to take it apart.

If a 22 caliber is legal in your state and you want to use it, go ahead. In my case, I generally use a .308 winchester with 165's, a .35 Remington with 200's or a .50 Alaskan with 300 grain Barnes originals. My thinking is a deer is the weight of a man (or more) and I want a humane killing cartridge...
