I maybe mistaken but when remington was making the shells for Hevi-13 they used the number 13 because they marketed them to shot 1300fps for most loads and or shoot sizes. I could be wrong but I have read it some where online but like a lot of things online are not 100% accurate.
Hevi-13 was never loaded to 1300 fps or was needed to. It was loaded and sold to mainly 1090fps for it does not need the speed like others to achieve the penetration as others do.
It is 13g/cc heavier than lead. It is 40% more dense than lead. EnvironMetal was the original Hevi-Shot. I still have about 8 boxes of it before Remington bought the rights to load and sell it before EnvironMetal got back on their feet and bought it back.
They were originally in a clear white Fiochi hull with a nickel case head. Un-buffered. Remington bought the rights, then went on to use flax seed as a buffer material.
In turkey loads, speed goes against you after a certain point. The fater the load, the more kenetic energy sets back the shot and disrupts the pattern. That's why most turkey custom loads are in the 1100-1200fps area. You will find some that are in the 1300fps, but as a rule of thumb, don't pattern as tight as the slower loads due to disruption upon being shot and the pattern being blown apart.
