One thing that's coming from their development is relatively high velocity, relatively low pressure loads for 'normal' 12ga slug hunters.
I don't recall the powders or loads with which they're getting the best success, but as I recall they've been using rifle powders and getting very consistent results in the deer-load range of performance as well as the full-house 12fh madness.
There's a lot of information on their 'road to success', and for the guys who want to run 12-bore type big game rifles that's the conversation to watch.
