I have never had any problems with Winchester 209 primers in either Remington or Winchester hulls, 2 3/4" or 2 1/2".

I know that once you use Fiocci primers in your hulls, you will have to keep using them because they are .001 larger in diameter than Win or Rem 209.

What type of hulls were you using? Maybe the primers weren't seated all the way.
