The curmudgeon sent me a reply that wasn't very promising, it just stated that BPI has over 300 loads using ITX. Hopefully they will come through with low-pressure data using components such as CB wads and remington hulls.

I've been shooting nice shot for a couple of years now and go through about 10-15 pounds a year. My Elsie loves nice shot.

I got my pressure data from Precision and I'm taking ducks with a 7/8oz load of #5 with authority out to 50+ yards.
