There is a long tracking shot and the first shot that was looked into the scope might seem like it was a straight through shot. The place of impact appears to be good, the animal reacts and then it all runs out into sparse blood, intermittent sign and much second guessing.
The placement of shots remains crucial as an influence on the result, but the way a bullet is made is what determines what happens when the projectile impacts too fast, at an angle, or against the bone. The errors listed below are not necessarily on the brand name, but on the incompatibility of design to actual impact conditions.

1. Using varmint-style bullets on animals that demand penetration
Rapid-expansion bullets have a thin jacket designed to disintegrate in small bodied targets. When the same design is requested to penetrate the vitals through deeper muscle, heavier bone or a mere increase of mass, the good hit may become shallow disruption and a running animal. An example that is in the field is one given by a hunter, about a 52-grain hollow-point projectile, marketed as a varmint bullet of the .22-caliber, which upon hitting its target (a coyote), exploded too violently to make a single follow-up shot. The building performed as it was supposed to perform, and that was to quickly incite and create a dramatic interruption, but to be more controlled in penetration was something that the bullet could not be able to give the application that was required.

2. Treating cup-and-core bullets as “universal,” especially at high impact speed
Conventional cup-and-core bullets are still quite effective within their range of operation. They have a higher probability of being upset by their thinner jackets and non-bonded cores to open large wound channels and quick kills at broadside on thin-skinned game even in ordinary ranges. The error lies in the fact that the same bullet is expected to act as a more robust design, at short range, with high-speed cartridges, at sharp angles, or on bone. Under such circumstances, cup-and-core bullets are not as lenient at high impact speed and fragmentation or poor penetration is more probable. One gets, as a consequence, commonly abundant shoulder meat, but insufficient penetration into the chest a circumstance that forms bad blood courses and slow healing.

3. Assuming a polymer tip automatically means “controlled expansion”
Bullets can be given a helicopter flight assisted by polymer tips, and the expansion can be triggered, but the architecture will remain the same. An inclined bullet may be still conventional cupandcore, and may still be subject to disintegration when impact velocity is great or when it strikes a dense bone early. This confusion is common as observed when hunters make generalizations of tips as one class. The engineering fact is less complicated: a tip is a characteristic and not a type of construction. Partitions, bonding, and jacket thickness, and shank integrity determine whether a bullet is continuing to drive after spikes in impact resistance.

4. Overvaluing unfired sectional density instead of terminal behavior
Sectional density is an approximate to penetration, which collapses with expanding bullets. The mushrooming of a projectile adds to its mass in front and may reduce its weight to take away the variance that actually determines the distance a projectile moves once it gets beyond the first few inches.

The examples of tests explain why initial SD may be misleading: two bullets of the same SD of 30 caliber with 150 grains can hit much different depths due to the difference in the diameter of the bullets recovered and the weight that retained after expansion. Practically, a hunter can choose a high SD bullet which still mushrooms excessively, sheds excessively and ceases when the shot must penetrate thick tissue.

5. Ignoring minimum expansion velocity at the far end of the shot
The problem of velocity is extended range performance which is a label on a bullet. There are constructions that can be opened consistently at slower impact velocity and those that require higher velocity to commence and continuously expand. When a bullet does not open it may punch a hole through with a small channel of tissue tear no long enough and usually not sufficient to hold a game animal with sufficient speed, particularly when placed off-center.

The thresholds of velocity differ according to design. A single summary of gelatin-based testing indicates that traditional soft points are expected to deform down to approximately 2,000 fps, bonded design to approximately 1,800-1,900 fps and a number of special-purpose designs to approximately 1,800 fps. When the shot is made at range, those numbers will count more than the muzzle velocity or the rating of the cartridge itself.

6. Letting hollowpoint style and tiny meplats create unpredictable terminal results
All of the hollow points are not hunting hollow points. The designs of some sharply pointed HP are optimised to be accurate or to be good with external ballistics, and the behaviour of their terminal performance is not repeatable a sharp nose may upset quickly or expand little, depending on the interaction of nose geometry and jacket thickness and the impact speed and tissue resistance. Gel testing and field experience on one of the technical overviews described sharp pointed bullets of HP as having extremely inconsistent terminal performance when they failed to begin expansion.

When that occurs in game, the strike may appear to be in the dead centre but cause little blood, great distance, as the wound passage does not enlarge as much as experienced by a designed big-game bullet. Construction of bullets does not substitute whether one will be shot or not, but it establishes the degree of error when actual shots hit the bone, angle, and inaccurate circumstances. A majority of the mystery track jobs are initiated at the design window of the bullet. The construction is matched to the speed of impact, anticipated angles and the structure of the animal, such that solid hits become an introduction to night-time sign-reading lesson.
