Has anyone else had reasonable success using rifles choked tubes in a side-by-side to create a poor-man's paradox? A friend has had good luck doing this with a Zabala 10-gauge. I'm just wondering if it is possible to get 2- 3-inch groups at 50 yards with, say, round balls of Fosburys loaded in Magtech brass shells with either black or smokeless. My guess is the wild card is how well the barrels are regulated.
Looking at using some sort of double with Greener crossbolt for this.
