These difficulties included the following: As monolithic bullets have developed, their performance in terms of penetration and weight retention versus hydrostatic shock varies.
Unlike jacketed hollow point bullets (JHP), FTMs do not rely on expansion to function as designed.
This is due to the fact that these bullets retain their size and shape far better than lead alternatives and therefore often penetrate more deeply.
Not only does this mean that the thicker, tougher skin of larger animals can be more effectively penetrated, it also makes the bullet more adept at breaking bone and delivering a terminal impact.
An additional benefit is an exit hole which allows for more efficient blood trailing, important for long-hair game such as bears.
In addition, there is less of a health hazard in terms of human food compared to bonded lead bullets.
