A 62 cal (20 ga) Trade Gun would serve you well and for accurate shooting you can improvise and temporary rear peep or open sight held in place by the tang bolt. I used that for developing an accurate load for mine, to remove the variability of shooting without a rear sight. Most trade gun shooters, in my experience, would tell you the 2-shot group in the photo is not typical of what to expect, except from an experienced expert, especially off-hand. A 5-shot group of about 2 " spread is certainly achievable at 50 yd with lots of practice, over a sandbag rest. Good enough for a deer or moose. Practice, practice, practice.
