If you have it in that book, I'm happy. I had a friend who used to load Bullseye in 12 ga. with 1/2 oz. loads but I never knew where he got the data. I'm happy to admit to being ignorant of the data you have. I have certainly been mistaken, thousands of times, in my 74 years of lip-flapping. I've never looked into the data on Bullseye for shotguns before and my concern antennae went up when I saw your post. The pressure and velocity you have sound just fine to me. I'd still be concerned about using buckshot(really big stuff) through an old full choke barrel. Does your data say anything special about buckshot, relative to choke?
Thank you,
