Great catch, Greg - I'm slipping big time..
my 20ga w/28" barrels are
not choked IC/MOD, they are choked Q1 & Q2. Further, I recalled Dean and a few others who have posted, sharing that they had 28" Q1/2 chokes. I guess I got that partially right, but clearly I mis-spoke.
In my defense, the gun is a 16ga.
