My Churchill Imperial sidelock XXV 2 inch chamber 12 bore at 5 pounds 3 oz. is just the ticket. Easily controled with 1 hand as you make your way through the thick stuff, and light and fast for that "poke and a hope". It fits me well, so it often connects; all I do is point and pull the trigger.
Best,
Mal
I am endeared to my Hellis 2" 12 for the same reasons, 26" bbls but light enough to manage with one hand.
In the early days of my hunting career I watched a buddy chasing a woodcock through some real tough stuff one day with a 28" Browning BPS. Made me go home and hacksaw the barrels of a minty 16ga Stevens 311 back to 22". Still have it as a reminder to leave guns alone, just buy another.
