As above. It never ceases to amaze me that some manufacturers apparently think changing the material but keeping the same shape as one of their lead pellets will give similar or acceptable properties. Changing any single parameter can have a dramatic effect on the overall performance of a pellet or any other projectile for that matter. It is all about getting the right balance between mechanics and aerodynamics.
