Hey people, read a book. More room in a hull is always good.
The very best 20 gauge loads are built in a 3" hull, not necessarily going for 1 1/4oz payload, but to provide cushioning and lower acceleration so the pellets are launched as undeformed as possible.
The 3 1/2" 20 promises more of the same. More room for wads and buffers. It might even be possible to make some adequate steel shot loads.
It does present some possible benefits for clever handloaders.
If you don't like it, you don't have to buy it.
