12 ga full choke for turkey is great, and best
Regarding deer rifle, i would reccomend 270, 7mm has a bit more recoil and more power than needed. 30:06 has kill d alot of deer as well as 3030, although not to sexy. I kill newely 20 deer a year and travel around the country and world to hunt. I would not recommend the 6, 6.5, 25 or 243 calibers. I too own some of them and truly have spent more time trqcking deer with them than my 270 or 300. Yes wirh perfect shot placement it is dead deer. But shots are not always perfect, so I prefer something a bit more meaty when killing for the freezer. Just my opinion, but there are over 500 dead deer behind my opinion that i base it on.
Awseome you are wanting to be back in the woods, good luck
