Disregard These 10 Deer Hunting Rifle Myths

Deer hunters have many questions, arguments and other discussions about deer hunting rifles and ammunition.

Deer hunters have many questions, arguments and other discussions about deer hunting rifles and ammunition.

One problem we all face is trying to ferret truth from fiction. We’ve all heard, at one time or another, that drinking coffee could be injurious to our health, but, as is often the case, that claim was followed up with a study purporting coffee as being good for our health.

For decades, we’ve been told that occasionally partaking of an adult beverage would likely kill our livers and turn us all into alcoholics, but now we know (or at least we might know) that an occasional indulgence could be beneficial to most individuals.

Such bogus and confusing pretenses aren’t limited to our health issues. We seem to have an equal amount of confusion within the shooting community. Following are a scant 10 of those misleading claims and my attempt to separate fact from fiction.

Damaged Bullet Points Hinder Accuracy
Through the years, many gun writers have warned shooters that flattened and damaged bullet points can severely affect shooting accuracy. The issue is one primarily a product of cartridges having been stored inside the magazine of a heavy-recoiling rifle. In such a case, when the rifle is fired, the cartridges sometimes are forced forward, causing the bullet points to impact the front of the magazine, thereby resulting in the flattening of the soft lead points.

It seems many shooters have accepted the pretense that such imperfections can cause a bullet to go astray in flight. Until a few years back, I had no way of validating or discrediting those claims, so, I decided to find out how large a problem this really was.

I began by severely damaging the bullet points of a diverse variety of cartridges. Those cartridges were then shot along with an equal number of pristine, undamaged cartridges at 100 yards. Test rifles were sandbagged front and back to ensure the maximum degree of steadiness. Without getting into a great deal of detail, I will only say that, at 100 yards, the amount of accuracy deterioration was so slight that I don’t believe any shooter under normal field conditions would notice the slightest degree of difference between the damaged and undamaged bullets.

Of course, whenever the aerodynamic lines are disrupted, a decrease in the bullet’s ballistic coefficient would result, and that would translate into slightly poorer trajectories and a reduction in the bullet’s ability to resist the effects of the wind. But, in most cases, and with the exception of shoot- ing at extremely long range, I believe the consequences would be minimal. What I believe to be a larger potential problem is the same heavy recoil could result in driving the bullets deeper into their cases. If this should occur, it could result in elevating chamber pressures. The best way to prevent this from occurring would be to tightly crimp the case mouths around the bullets.

Can a twig or small limb affect your bullet's flight?

Can a twig or small limb affect your bullet’s flight?

My Bullet Hit a Twig!
I’ve often heard hunters attempt to justify a missed shot because the bullet clipped a small limb or twig on its way to the target. Even the legendary Jack O’Connor occasionally used this as an excuse for a failed shot. It’s certainly logical that a bullet encountering an obstacle could be disrupted, but I was at a loss to as to how serious a problem this could be.

In an effort to find out, I constructed a type of wooden manifold, wherein I inserted a series of hardwood dowels to simulate limbs. The dowels were positioned close enough to ensure that a bullet traveling to a paper target on the other side would be sure to contact at least one.

Three calibers were selected for testing: the .300 Win. Mag., .30-30 Winchester, and .22-250 Remington. Because of the current variety of .308 bullets, three different bullet weights and styles were shot in the .300, with one style for each of the .30-30 and .22-250.

I began with doweling measuring 3⁄16-inch and placed the obstruction 10 feet in front of the target. In my first rounds of testing, and in all calibers, the amount of deflection was nearly indistinguishable. So, next, I increased the dowels to 1⁄4-inch and moved the obstruction 30 feet from the target. This increased group sizes, but still not substantially. Of course, as the size of the object struck increases or the distance between the obstruction and the target is increased, you should expect a greater degree of deviation. The important thing is that shooting through grasses and fairly light vegetation should not be problematic for a hunter, as long as the game is a reasonable distance behind the interfering obstacle.

Round nose, tipped, lead … what’s the best bullet for shooting through brush?

Round-Nose Bullets Penetrate Deeper and are Better in Brush
My previously mentioned bullet deflection tests included pointed and blunt-nosed bullets. After seeing no noticeable difference in the amount of deflection between them, I decided to take the tests one step further and see if blunt-nosed projectiles had either or both a tendency to penetrate deeper or retain a higher level of retained weight when shot into a bank of old magazines.

You have to be a bit careful, when drawing a conclusion like this, because these traits are closely related to the quality and construction of the bullets. Nevertheless, as long as the bullets were of the same high-quality construction, I saw nothing in these tests to indicate that a round- or flat-nosed bullet would perform any better.

Pointed bullets routinely carry a higher ballistic coefficient and, for that reason, will buck the wind better and shoot flatter at long range. That makes it an easy choice in my own mind, regarding which bullet style to shoot. As long as you aren’t shooting a rifle with a tubular magazine that requires the use of blunt-nosed bullets for safety reasons, my choice will always be pointed projectiles.

Stainless Guns Require Less Maintenance
The trend in firearms clearly seems to be away from the classic blued ones and in favor of those being marketed as stainless. But, a big misconception comes into play when a person thinks these stainless in appearance firearms are impervious to rust. In reality, they are every bit as susceptible to rusting as a blued gun — it may take a little longer for the rust to take hold, but rust they will, if proper precautions aren’t taken.

The reason is based on the fact that, while the gun metal may look like stainless steel, it really isn’t stainless at all. Because of this, it is advisable to take the same precautions to prevent rust on both blued and these so-called “stainless” guns. The best protection comes from thorough cleanings and frequently wiping down the metal surfaces with an oil-soaked rag.

Bore-Sighting is a Good Way to Get Your Rifle Zeroed
Bore-sighting a firearm should never be considered an alternative to actual live-fire zeroing on the range.

Just because the center axis of the barrel may be perfectly aligned to the crosshairs of your scope does not necessarily mean your bullet will follow that same line of flight. In fact, it rarely does. Bore-sighting should be used only as an intermediary step, after which actual live-fire shooting should follow to fine-tune the adjustments.

But the usefulness of a boresight is not limited only to getting your initial shots on paper. Once you have completed the sighting-in process, you should take another reading, followed by recording that relationship on paper. That way, if your gun gets bumped hard or dropped, you have an easy way to confirm no ill effects have occurred.

I Always Let Someone Else Sight-In My Rifle
Some shooters who have a tendency to be recoil-sensitive may be inclined to let someone else sight in their rifle for them. This should, however, never occur. There are several advantages to sighting-in your own rifle.

First, it gets the shooter used to the recoil of the rifle, and, second, it familiarizes them with the gun. But aside from those very valuable advantages, it is important to recognize that differences in how people actually see things can effect where the bullets will impact on a target. Different shooters shoot- ing the same rifle and ammunition will quite often have their bullets impact at a different point on a target.

A Clean Firearm is a Better Firearm
How could anyone make an argument against firearm cleanliness? Well, I can think of only a single instance when a little dirt might be a good thing, and that is inside your gun barrel when it comes to heading out for a hunt. One of the factors necessary for consistent shot placement has to do with the consistency of the firearm bore.

Simply put, a round fired through a clean bore will almost always impact at a different point that those shots that follow—and that first shot is often the most important you will take in a hunt- ing situation. I have frequently found the amount of variation can be from about an inch all the way up to three or four inches at 100 yards.

If you never shoot past 50 yards, this might not be an issue of concern, but, if you find yourself trying to pull off a shot at a record-book bighorn ram on that once-in-a-lifetime hunt at 400 or 500 yards, it could easily become a substantial problem to overcome. I like to remove all the variables I can and, in so doing, I always send a round down the barrel and foul the bore before heading out to hunt.

I Always Carry my Rifle Muzzle Down in the Vehicle
When traveling, it has become a common practice for many shoot- ers to position their rifle with the muzzle down against the floorboards. I suppose most believe that placing their rifle in this position provides a degree of safety, but there is a problem in doing so.

The condition of the barrel crown is crucial to good accuracy. Floor- boards, particularly in hunting rigs, are frequently dirty, and this dirt can easily result in a marring of the crown.

A better way to carry a rifle in a vehicle is in a carrying case, but, some- times a hunter likes to have their rifle more accessible (for obvious reason). If you fall into this category, and as long as the rifle is unloaded with the action open and the muzzle is pointed in a safe direction and away from people, carrying it upright, muzzle towards the truck roof, simply makes good sense and can go a long way towards prevent- ing damage to your rifle that can affect its accuracy.

My Rifle Shoots Better at Long Range
I have occasionally heard shooters purport that their rifle shoots more accurately at long range than at close range. This is simply untrue and cannot be.

One of the major factors in accuracy has to do with the yawing of the bullet. Yawing is when the back of the bullet begins to wobble in flight. This eventu- ally results in the entire bullet moving about in a circular manner, as it makes its way to the target.

The theory is that the yawing even- tually begins to settles down, result- ing in a lessening of the size of the bullet’s circular movement. Neverthe- less, whether the yawing is lessened in flight, when the bullet initially starts to oscillate its destiny is then cast. Having begun these movements, it is impos- sible for the bullet to lessen the size of its rotation and get itself back on a straight-line track.

In reality, if your rifle is capable of shooting, say, a two-inch group at 100 yards, it won’t be capable of one-inch at 300 yards. In fact, under the best condi- tions, that same rifle will most likely shoot a six-inch group at that range.

You Can’t Beat Factory Ammo with Handloads
Without a doubt, factory-loaded ammunition never has been better than it is today. A shooter has more choices in bullets styles and weights than ever were available in the past.

But mass production can never equal attention to detail—and that is why factory loaded ammunition virtually always falls short in the area of accuracy and performance, when compared to handloads.

For years, it puzzled me why that was the case. The factory frequently loads the same bullets that handloaders use, using the same primers and cartridge cases, and, while the factory seldom divulges what types of powders they’re loading, I believe their choices are of equal quality to what handloaders use.

I eventually decided to investigate the situation a little closer and began pulling the bullets from a wide variety of factory-loaded cartridges to check the weight of the powder charges.

I took five cartridges from each manufacturer and each load type, weighed the charges, and what I found shocked me. While most handloaders attempt to hold their charges to within plus or minus 0.1-grain or less, apparently the ammo factories aren’t so critical. To my surprise, the factory-load charge weights varied from a low of 0.5-grains all the way up to a whopping 1.7-grains! In most cases, I found the cartridges containing the heavier powder charges usually possessed the largest amount of deviation in their charge weights. Also, it was the larger cartridges that typically contained the coarsest grained powders, which can pose a problems when it comes to metering accuracy.

I wondered how such a slack standard could take place, so I followed up by contacting several mainstream ammo manufacturers and was told by each one that their powder charges are metered in volumetric form, rather than being measured by weight. Of course, the factories usually run their own in-house checks to make sure they fall within their preset standards.

But my issue is with what those standards are, when it comes to fluctuations in powder charge weight. I am quite sure that, if my own handloads contained powder charges that varied that much, my loads would be shooting on par with those of the factories’.
