Didn't someone say that Federal...

[poorhunter]

was going to make their Heavyweight WITHOUT the Flight control wad this year. Or that they at least improved it?

Sounds like they have modified it a bit, saying it's ok to use in ported chokes.

From what I've read/heard from several sources, you better buy all the Heavyweight you can get if that's your load of choice because they will be discontinuing it in favor of the TSS. And yes the new FlightControl FLEX wad is said to be an improvement of the original allowing use in ported chokes.
