I was out in my shop tonight doing inventory on reloading components when I decided to inspect the shells I had left over from last spring. They had been stored in an MTM plastic shell holder in my shop where the temperature varies from 30-35 in winter to maybe 90 in the summer at times. To my surprise, 5 of my HEVI-13 Magnum Blend loads has leaked out buffer, 2 leaking a lot and other 3 a little. I plan to make HEVI aware tomorrow and see what kind of customer service they have.
