It will be harder to beat the cheap Primos tightwad. 660 choke especially with hevishot magnumblends. Out of all the chokes i tried it shot the best and only cost $15. Shooting 200-215 at 40 with the magnum blends. Hadn't tried the winchester longbeards. I got my Primos tightwad on ebay cheap. You won't find one that says Mossberg 535,but it is just a standard invector choke.
