I bought a new Nova this year and I havent found a choke Im satisfied with yet. Tried three different chokes & 3 different shells. None seem to pattern well.
The best one so far is the full choke that came with gun. Had trouble with the 2 turkey chokes I tried Primos tight wad & my brothers turkey choke out of his Stoeger. They swelled up after shooting a shell through them had trouble getting them out of gun & there is no way I can get them back in. I was shooting Winchester & Federal turkey loads 3 inch 5 shot.
