I currently own two shotguns – a 20-gauge that I bought last year and a 12-gauge that I bought this year.  Both are Benellis.  The 20 a Montefeltro and the 12 an Ethos.   I’d been alternating guns a bit this season but recently noticed a trend.  When I carry the 12 gauge I don’t see any birds.  I mean none.  I haven’t even fired a shot out of that thing in the field.   When I carry the 20-gauge I see birds and have shot all my birds this year with it.   Now I’m superstitious and am sticking to the 20 the rest of the season.
