Ideally, most of us "avid" turkey hunters probably "need" at least two very different dedicated turkey shotguns.
This is what I have:
1) A
VERY heavy 12 gauge autoloader. It's made about another pound heavier by the 1.5-4.5 scope & mounts.
This becomes my gun of choice when it's more likely for a longer shot, and if particularly, I plan to be walking less ---- often the case in early season when the woods are so much more open.
Typically, I am loading with 3 1/2" shells, but some with only a 1 7/8 oz payload.
Even with this gun, there is a huge difference in the felt recoil of these shells vs. some 2 1/4 oz loads I've patterned, which are absolutely brutal.
2) A
VERY light 20 gauge autoloader. It's topped with a Burris Fastfire sight which barely weighs over an ounce.
This becomes my gun of choice for much if not most the season, and if particularly, I plan to do lots of walking. Also, once the spring green-up gets well under way, typically around mid-April, the kind of set-ups I typically choose, these usually only enable me to even see a turkey under 40 yards. Often, my first view of an old Tom is his red head bobbing up like a periscope, just over the horizon, but only 40 yards away.
The next view may be when he steps out from behind a large oak, some 20 yards away. At this moment, a wide field-of-view optical sight becomes an advantage, as does
NOT having such a super-tight choke. Am typically loading that 20 ga with #7 Federal Heavyweights, which, even with their 1 1/2 oz payload, don't "kick" me half as hard as that heavy 12 with only 1 7/8 oz loads.
Practically speaking, I believe the 12 gauge is only providing me about 5 extra yards of high-probability range, basically 45 yards with the 20 ga vs. 50 yards with the 12.
So why punish myself when most birds are killed well under 35 yards?
I'm sure many who hunt mainly large fields and have little woods to hunt will disagree, but for me, even doing quite a bit of my hunting around some good-sized fields, hunting with the 20 gauge just keeps getting more "enjoyable" than unnecessarily carrying around that piece of 12 gauge artillery.
