I was wanting to use my nova 12g for coyote hunting yesterday but when I tried to put my modified choke in it would not fit. I remember when i was taking it out it was a little tight but now it will go in about half way and stop. The other chokes i have are turkey super full and a carlson's mid range blackcloud choke. The turkey choke is out of the question for buck shot, what about the carlson's mid range blackcloud? Can I shoot buck shot though it with out scratching or even having it blow up in my face?
