Measuring a random sample with a micrometer showed that the head has a smaller diameter that the tail, ranging from 4.35 mm to 4.45 mm, averaging 4.4 mm. That accounts for the sloppy fit and depending on the barrel may not engage rifling.
The tail edge comes in at 4.55 to 4.7 mm diameter and should deform to hold the pellet in place until fired. However the material is quite brittle and rather than deform may simply snap off so the pellet falls through the barrel. This can be resolved by loading the pellets leaving the tail edge protruding just a tiny bit rather than inserting it flush with the edge of the barrel.
Used in pistols the spread is considerably larger than the Vortex Eco that I normally use. The Vortex are made in Germany, are larger and very consistent but also cost more than twice as much.
In rifles the difference is less noticeable.
The pellets have a flat face and cut paper targets very cleanly, particularly at high velocities.
