In the 28 and 410, the AA HS still rule the roost.
12 and 20, STS or Gun Clubs are the way to go if you dont want to mess with AA HS in those gauges.
All true. Lifespan of .410 HS is about 50% better than the older CFs. And you can juice them to well over 1300 fps.
But, like Bobski, have a metric crap-ton of old-styles in .410 and 28. (well, also 20 and 12) So I give or sell my HS hulls in .410/28.
A minor advantage favoring old .410s and 28s, required powder charge is less.
