Looking for help in where to get data as the title says. I found some for Cheddite hulls, but I don't have any of those. Have various brands of primers, wads, and some different brand hulls just no Cheddite's.
Thanks in advance,

ballistic products might be a good place, and have you looked though alliant powder and Hodgdon web sites
Forget BPI, or Alliant. They don't have anything. Hodgdon has some good data if you like velocity. If you are trying to extend your range, buffered loads are the way to do that, and the Tom Roster buffered lead and bismuth manual is about as good as it gets. The following load is from it, I like this load. I'd recommend #5 bismuth with this.
20ga Federal 2 3/4"
Federal 209A
21 gr Bluedot
Winchester WAA20F1 wad
7/8oz bismuth
18gr PSB buffer
fold crimp
1175 fps
11.900 psi
P.S. since the WAA20F1 has been discontinued, I'm using the Claybuster CB1078-20, which is kind of a cross between the WAA20 and WAA20F1. It loads fine for me. I make no claim to the safety of this, but I do it.

Thanks megasupermagum, I have everything you list except the buffer medium. Where do you get that ?
Precision Reloading carries PSB buffer.
I’ll just go ahead and ask my question here. Do you happen to know or would you mind measuring the ID of your shot bushing that throws 7/8 oz of bismuth ? Also I assume you are using a Lee dipper to measure the buffer, what size dipper gets you 18 gr. ?
FWIW , I load Bismuth in the 10 down to the 28 gauge . I usually only load twenty five or so at a time . I weigh the Bismuth for each shell . Slows down the process but no more of it than I shoot . Smallest Bismuth I load are #4 that stuff bridges easily in 20 and 28 gauge drop tubes .

Thanks 6pt-sika, I've run into that bridge problem with 7 1/2's in my 410 loads. I tap the drop tube with my plastic bullet puller on every load. Like you said, it is a slow process, but I'm retired so time is what I have that is not very costly.
I believe it’s MEC that will tell you to tumble the shot with baby powder then drop them in the shot bottle .
