I had good groups with slugs in my M4 using the factory MODIFIED choke. I used 50yds for my zero.

I would try your modified and your improved cylinder. See which works better. I seem to have more luck with my improved cylinder when shooting rifled slugs. Also, you may want to try to find a rifled choke for your gun.

What's the purpose of a choke tube? To tighten up the spread of the shot. Since you only have "one shot" with a slug a cylinder choke should work fine. (After all do rifles use choke tubes?) Definitely do NOT use any choke greater than a MOD choke. I had excellent groupings with a improved cylinder choke shooting slugs with my M4 yesterday shooting Remington rifled slugs at 50 yards. Interesting, switching to Federal True Balls rifled slugs moved the grouping up 1 foot and spread them out a little more. So I'd recommend using your most open choke and try various different slugs to see which works the best.
