RIO 209 PRIMERS

Rio primers have a large diameter. I used them in Fiocchi and Federal Field and Target hulls with no problems.

I wouldn't use them in hulls and then mix those hulls with hulls that had smaller primers in them unless you plan on using only Rio primers.

Some primers may fall out of a hull that had a Rio primer in them.
