Primer Substitution: 10 Gauge Load

[Paul Harm]

Mark, I think you took my last reply the wrong way. What I was trying to say was Cheddite makes two different size primers, a European size, and a American size primer. I have measured Cheddite 209 primers and they are the same size as Win primers. I know I can go from Win to Cheddite and back without any problems with fit. On other reloading web sites guys have said about problems with fit if they get the wrong Cheddite primers. I know RIO primers are bigger. Hope this clears things up a bit.

I have never heard they made 2 different sizes before . I know they make different strength primers . But the only ones I have seen available here are the Clerinox CX2000 type 209 . Which are the ones I use that in Cheddite hulls that stay put . They measure slightly larger than American made primers . If I use any of the American made primers in Cheddite hulls they are a loose fit unless you condition the primer pocket first . I haven't had to buy any new Ched primers in a bout 5 years or so maybe they changed them .

Which Cheddite primers are you using ?
