I see 0 reason to hunt deer with a 12ga slug gun now that I use a 20ga Savage 220.

less recoil is nice, but almost non-existent in my decision to now shoot the 20ga over the 12ga.

Saying you like the extra power of the 12ga over the 20ga is like saying you prefer to deer hunt with a .375 or .458 over a .270

I mostly see it as a masculine peeing contest among Man-boys.

But then again if you plan to slug deer at over 200yds, well maybe then you should get the 12ga, but 200yds with my 20ga is plenty far for me. Plus I feel my 20ga is way more accurate at 200yds than any 12ga is, but I'm sure others would argue differently.
