A couple of years ago at an auction, I won the bid on a box of reloading stuff which contained 6 boxes of #57 shotshell primers. Knowing they were to small to fit in modern hulls, they sat on the shelf. Even though I have plenty of primers, with this reloading component pandemic going on, I decided to test the soda straw trick. Cut the straws about 1/4 inch long and found they were a nice fit on the primers. With the shortened straw on the primer, they fit into some once-fired Winchester HS hulls I had. Not a tight fit by any means, but they stayed in place. Went to shoot a round of trap today, and to my surprise all fired and there was no problem. Now I'm wondering if I can use these same hulls again with the soda straw primers or if it's a one time deal.
