I already reload a box with the "straw technique".
Everything looks ok, but until I fired them, I will know if the plastic straw seals or not (someone here told me, via private message, that it will perform perfecty!).

I reload about 2-300 shotshells a year, so if the straw technique is fine, I have primers for the next 5 years!

Thank you all!
