The Speedloader Swift was designed to be tough.

We made sure that shells stayed firmly in place when shooting but released instantly when needed, this meant choosing a material that is flexible enough to bend and then return to its original shape successfully, time and time again.

Our final choice was polypropylene; its flexibilty and strength outperformed all other choices.

It also performs across a huge range of operating temperatures including sub-zero. (Read the post about an article from top Swedish shooting magazine Min-Jakt to see how they performed).

The tests revealed that the device performed well, and could be used and discarded effectively while wearing gloves.
