Do not assume the gun with a tighter choke will group your shots tighter.
I learned this years ago patterning some shotguns i have.
The gun that shot the tightest patterns was a full choke and was not the longest barrel.
There is a lot of differences in chamber shapes in a shotgun and a longer gradual taper into the barrel may result in a tighter shooting gun.
The absolute tightest shotgun i ever shot was Homemade muzzleloader rifle shotgun.
Some 1:36 twist 50 cal that stuck a bullet in the tube and we drilled it out and made a smooth bore from it and hacked the barrel short.
It shoots tighter than any 12 gauge I have.
Pattern what you plan to shoot just so you know what gives.
You probably do that anyway.
