Buzz,
I'm not trying to be a smart ass, but, as I already posted, I don't have bore or choke measuring equipment for 20 or 28 gauge. I HAVE stuck a dial caliper in the end, but, you need to know more about the entire bore of the barrel to form up an opinion of how a gun is choked. That, and a bit of shooting it at paper, anyway. Let me stress this is my opinion only, and if someone else's differs, I won't argue it with them.
Having said that, I think I can state that the 28 gauge Darne would be the better option vs. the 20 gauge for this early season trip.
Thanks for the well wishes.
Lloyd,
I have options. 16 gauge Nitro, choked cyl and mod, lots of pumps that never see the light of day, 12 Darne with little and less choke, 28-I have time to process it a bit.
But, the 28 would be a dandy choice, no?
Best,
Ted
