The old standard of 1,000 foot-pounds on game of the deer size, quoted so long by Col. Townsend Whelen, and yet still quoted today, serves as a way of sanity-checking a cartridge: does it have enough margin to drive the hunting bullet into the vital organs and not burst before it reaches its target or jam in solid tissue? It did not substitute shot placement, but it certainly made a point of shedding light on the same thing experienced trackers will find out through hard experience, that when the penetration is marginal the follow-up is long.
Bullet engineering in the modern world reduced the distance. Controlled-expansion designs are able to be held together, expand more predictably and continue to drive upon impact with bone. But building cannot convert a projectile of light caliber to a projectile of heavy caliber, or can give it a velocity which at range is no longer possessed. The last book is still written by physics.
These cartridges may be wonderful down their own running, varmints, predators, steel, or long-range woods work. The problem begins once hunters request them to undertake big-game work where sectional density, impact velocity, and bullet integrity cannot be compromised.
1. .223 Remington
The low recoil, high practical accuracy and flat enough trajectory of the .223 Remington endears itself to small target enthusiasts. That comfort can tempt the hunter into exceeding in its bore diameter and length of bullet weights that which its construction was designed to withstand. Although muzzle energy may appear respectable on paper, the cartridge dies away soon when heavy muscle, thick ribs or a skin crease of a shoulder are included in the angle.
The choice of bullets is important in this case than in larger rounds, since tender designs effective in varmints may suddenly fail in large-bodied animals. The wide range of contemporary hunting bullets such as cup-and-core, bonded, partitioned and monolithic, can justify the reason. Harder bullets will be able to hold their own weight and punch deeper, yet the .223 would still come at with little frontal area and little momentum than the traditional deer-and-elk manna.
2. .22-250 Remington
The .22-250 is a velocity specialist. The fact that it is easy to strike a coyote dashing a fence line makes speeding easy, and it is easy to holdover on open terrain as well. On bigger animals that same speed may be a liability, since the light bullets may expand excessively and lose their energy before they can reach the vital organs.
It is the archetypal type of fast, light and dramatic wound track that appears spectacular on gel but does not always address the actual issue that is deep, consistent penetration through mixed tissue and bone. In case the angle of the shot is not ideal, the margin is eliminated.
3. .243 Winchester
The .243 Winchester is on a razor blade: it has the universal baking and is known to work well on deer with the right bullet but as soon as elk or moose are brought up it is debatable. There has been enough stories of clean kills by the hunters and there have been enough stories of guides preferring the client to arrive with more cartridge than the minimum require.
It is an engineering fact that the construction of the bullets becomes the main one. A harder bullet can continue to move on hitting and to be heavier than a traditional more soft-designed bullet, and this is the reason bonded or monolithic designs are commonly employed where hunters attempt to scramble the.243 in the upward direction of the animal size. Nonetheless, larger animals introduce fat bone and deeper vital areas, and a small-diameter bullet does not have a lot of leeway as the angle is steeper or the shot is a few inches off the mark.
4. .30 Carbine
A historical cartridge with a cult following, 30 Carbine is a cartridge whose ballistics exist in the same realm as the hot handgun world rather than the current big-game rifle world. Its 110-grain bullet has but limited penetration and limited reach, the latter being increased by the former, when a hunter is reduced to a quartering shot, or must weave his way between brush and deep cover.
In close quarters on small to medium game, prudent choice of bullets and practice in shooting can succeed. It performs poorly where it is expected to act as a deer-and-bear rifle cartridge. It does not store the same amount of velocity or energy to continue expanding and continue driving once struck.
5. 7.62x39mm
The 7.62x39mm is robust, widespread and popular with lightweight rifles. It is able to do honest work within conservative ranges in the deer woods, especially with bullets designed to expand in a controlled manner. The constraint is apparent with increasing distance, with velocity, and hence useful upset, decreasing rapidly.
Impact performance is linked to the fact whether a bullet is traveling fast enough so that it is expanding as intended. Most contemporary hunting bullets have a minimum impact velocity expansion threshold, and the 7.62x39mm expands sooner than traditional.30-caliber hunting bullets. After that, it is able to drill through with a small way instead of causing the type of internal damage that shortens tracking work.
6. 5.56 NATO
There is an overlap of a bore diameter of .223 with NATO and the field constraints are mostly a rhyme; small diameter, light bullets, and limited penetration of large game. The pitfall that is taken up by hunters is to think that in military cartridge, you have the implication of big-game capable. Controllability and loadout logistics can be the priorities of the military design, unlike bone-breaking penetration in a shoulder or thick ribs at odd angles.
In its lane in its predation, in its varmints, in its practice–it glows. It requires the highest discipline in the choice of bullets, and the position of the shot, and even then it has but few concessions, when things are not at their best.
7. .17 HMR
17 HMR is a high-accuracy rimfire that impresses a lot with the accuracy of its kind, and it is incredibly useful on small varmints where the insignificance of recoil and flat trajectory is important. The issue is easy enough, the cartridge lacks the capacity to store energy or the weight of a bullet, to reach an anatomy of big-game scale. When hide, bone and thick muscle come into play, penetration becomes shallow and intermittent.
Legality in most instances is a reflection of ability. A cartridge that has proven to be effective in sending small pests is not necessarily versatile in an upward direction and.17 HMR is the obvious example of a round that should be left alone.
