That's a hard question to answer. You can take 3 identical guns to the range and they may all pattern differently due to small variances ion the barrel, choke, etc.
As for scopes that's kind of personal preference. My first few turkeys were taken with open sights, the last one with a red dot. My gun now wears a 4x scope as it double duties as a deer gun (the scope is receiver mounted). I found the red dot easiest to use myself.
I was unaware red dots could be used out side in the day. I'll have to look into one.
Thank you.
