Cheddite primers are good. They are a lil tougher seating than say Win 209 but you shouldn't have that problem since the hulls are primed already.
Bought some about 20 years ago, and recall no problems with them. I think I ran them through a sizemaster mec, so do not know how much adjustment a grabber or other progressive press might require. Seems like these were 28 ga.
I've been using the cheddite primers in everything from 410 to 12 ga. without problems. Powder valley had a good price on them and I tried them because of that. I'm happy with them.
I bought some hulls that were already primed and when I read the description, it said they were "cheddite" primed. I have not heard of that before. It got me to thinking along the lines of boxer and berdan primed. I was already making plans on what to do if they were corrosive primers.
I'm also looking at some videos about "roll crimping" and I want to try that out. I think I'm going to make some 00 buckshot rounds.
