I have subscriptions to English shooting magazines including the Field and Shooting Gazzette. Traditionally quarter & half (about IC-Mod) has been most popular, but they report there is a trend towards using even more open chokes with today's modern ammo at driven shoots.

I've shot English doubles with open chokes and found they work great with good cartridges.

The Hussey should be perfect.
