Advice in loading Cheddite 2-3/4"

It has been decades since I had loaded shotshells so when I started reloading again I figured, as before, the info in a manual would be pretty close to what was needed. So I pick up some Cheddites and some Downrange 12S-3 (1-1/8 oz) wads. In loading and then crimping, something doesn't seem right...the crimp seems too deep. Measured the shot drop and it weighed out correctly. I've included a picture of hull and wad. Click on the thumbnail to view it full size. It looks as if the wad is too short (1-11/16") for this shell. Although, this wad fits beautifully in a Federal case. Wrong wad? I've blackened the wad petals so they are more distinguishable. Anyone use Cheddites with 12S-3's?

 

I use 12So in place of 12S3 with an 1 1/8 in a GM hull. What does a primer have to due with the crimp?

 

Let me clarify...I was referring to the hull which is also Cheddite. I don't understand your question, although the primers are also Cheddites I didn't mention primers at all.

 

I'm sorry, my mistake.

 

You need to check the base wad height compared to Federal and AA hulls. The rest is easy

 

No biggie...I appreciated the insight to the different wad use.
