Rage Broadheads

Broadhead Effectiveness

The Thunderhead 125 is an excellent choice for those desiring this design. Robb has used it on everything from small North American deer to large-bodied South African plains game to brown bears in coastal Alaska.

The debate over broadhead size, weight and style has been going on for centuries. What’s the answer for modern bowhunters?

A few springs back I was turkey hunting in northern Arizona. Walking along the banks of a creek something caught my eye. I stopped and looked again, trying to figure out what it was. There! The angle of the sun was such that it briefly glinted off something shiny. Reaching down I found it was an ancient obsidian broadhead, one about the size of a 50-cent piece and still in perfect condition. I walked down to the creek and, when I washed the mud off, was mesmerized by the way the sun shined off the angles knapped into the sides of this ancient tool.

The broadhead is the ultimate connection between the bowhunter and prey. We all understand how difficult it is to get a controlled, close-range bow shot at an animal. When we do, the success or failure of the day is totally dependent on whether or not the broadhead does its job. If it does, we whoop and holler and give thanks to the stars above for our good fortune. If it fails, at best we eat tag soup; at worst, we wound a magnificent game animal and return to camp in shame. Fortunately, today’s broadheads, regardless of design, are truly effective tools of predation.

History Lesson

montec broadhead
The G5 Montec is an old-school traditional fixed-blade design with blades that must be hand-sharpened. It is an excellent broadhead.

In my little home office is a very small collection of ancient broadheads crafted from obsidian and flint by hunters who had much more at stake when it came to sneaking within arrow range of game than we do today. I’ve stumbled across them from time to time as I have traveled the country bowhunting with modern archery tackle, and each time I do they send me off daydreaming about those who came before us.

Upon reflection, one can see that broadheads have really not changed all that much through the years. For example, you can find three-bladed broadheads made from metal that date back to the Bronze Age, some 3000 years ago; a design very similar to the Trocar tip popularized by Muzzy was built in the 14th century. Its function? To penetrate the chain mail worn by soldiers.

It wasn’t all that long ago when bowhunters were shooting what were, by today’s standards, large, heavy broadheads that impede arrow speed. Traditional-style, fixed-blade heads have a lot going for them, though. They are built from one-piece construction featuring a main flat blade generally made from welded steel, and are incredibly strong. Their cut-to-tip design fosters deep penetration, and the combination of heavy head weight and relatively heavy arrow shafts with their bulletproof construction and razor-sharp edges help them penetrate deeply and crack even the heaviest rib bones. Bowhunters using longbows and recurves still often choose traditional heads.

The old traditional broadheads often weighed upwards of 200 grains, though modern versions can weigh as little as 100 grains. Perhaps the biggest downside in using any of these heads for the modern bowhunter is the fact that their blades must be hand sharpened, a basic woodsmanship skill that most of you in the younger generation were never taught.

It was the need for consistently razor-sharp blades that spurred the development of the most popular style of broadhead used today, the replaceable-blade design. Many of today’s bowhunters have never known a time when this style of head was not available, but the basic concept dates back to the 1950’s, when innovative California bowhunters like Jim Dougherty, Jack Doyle and Duke Savora experimented with gluing razor blades from their shaving kits to the three most popular broadhead styles of the day–the fixed-blade MA-3, Bod-Kin and Hill’s Hornet.

The technique became relatively common in the region and was a precursor to today’s popular replaceable-blade designs. Doyle began marketing the Zia Scorpion, which was the very first razor-insert broadhead, as well as blades for the glue-on process, in the early 1960’s, advertising both in the now-defunct Archery magazine. Duke Savora’s Swept-Wing broadhead, introduced in 1974, was the first mass-produced insert-style head that used replacement blades designed specifically for broadheads. It helped set the stage for the well-designed replaceable-blade broadheads that dominate the contemporary market.

If bowhunters are one thing, they are tinkerers. Looking back, it now seems that what we once thought was off-the-charts radical–the mechanical broadhead–now seems a natural progression that came about by those trying to achieve increased terminal performance and, above all else, accuracy. Though I have never had a problem tuning even a fast compound bow with a replaceable-blade broadhead, some shooters do, and so they began turning to mechanical broadheads that have nearly identical flight characteristics as field points.

To be blunt about it, the first mechanical broadheads basically sucked. They had all sorts of design flaws, were flimsy and didn’t always perform as advertised. Many bowhunters were disappointed with them for a brief period, and their future was in doubt. Today, of course, mechanical broadheads have evolved to a point where the best are easy to tune, are strong, have razor-sharp blades and can penetrate as deeply as the best replaceable-blade styles–and their popularity has soared.

Also gaining some ground in the recent years are so-called hybrid heads, which feature two fixed blades and a pair of mechanical blades that open on impact.

Fact vs. Fiction

Rage Broadheads
The 100-grain Rage Hypodermic is the top-selling mechanical broadhead today. It flies great, penetrates deeply, and holds together well. This head went through both front shoulders of this 295-pound Kansas whitetail.

It is hard to quantify broadhead performance en masse simply because it is difficult to collect data in sufficient quantity to make a judgment. However, a study presented at the Southeast Deer Study Group in 2014 by Andy Pedersen, a retired senior engineer at Naval Support Facility Indian Head, a military installation on the Potomac River in Maryland, tells us a lot. The base is involved in explosives manufacturing and research, among other things, so the public is not allowed on site. Prior to 1989, sharpshooters were used to control the overpopulation of deer. In 1989, the base’s Natural Resources Office established a formal bowhunting program open to military and civilian employees to help maintain the deer population within the carrying capacity of the habitat.

During this study, hunters were required to file reports on whether they shot at, hit or recovered a deer (defined as found within 24 hours). The base’s Natural Resources Office collects biological data, such as live and dressed weights and jawbone age, from every deer killed. The base is not large or heavily hunted. Two areas totaling 3,000 acres are open to hunting; on one of the areas, there is an earn-a-buck requirement, and bucks must net 130 SCI. On the other area, there’s no earn-a-buck requirement, and bucks must have at least three points on one side. A total of 209 bowhunters pursued deer on the base in the 24 seasons in this study.

A total of 135 of the 209 bowhunters recovered at least one deer, dragging out a total of 1,083 deer after putting in 35,011 hours of time on stand. That’s one deer for every 32.5 hours in the field, and an average of about eight deer per successful bowhunter. To get 1,083 deer, hunters reported hitting 1,296 deer from 1989 through 2012 for a recovery rate of 83.6 percent. Separated by bow type, crossbow hunters had an 89 percent recovery rate compared to 83 percent for compound bows. The average shot was a tick under 20 yards.

Weighing broadheads
One thing Robb recommends is weighing your broadheads to make sure you have a quiver filled with heads that weigh closely the same.

When it comes to broadhead type (for both compound and crossbow users), hunters using fixed-blade broadheads recovered 82 percent of their deer (874 recovered out of 1,066 hit). Hunters using mechanical broadheads recovered 91 percent of their deer (209 out of 230 hit). The total number of deer is lower for mechanicals because they have only been approved for use on the base since 2007, although the majority of deer shot since then were shot with mechanicals.

Compound bow shooters using mechanicals recovered 143 of 161 deer for an 89 percent recovery rate; those using fixed blades recovered 821 out of 1,001 deer for an 82 percent recovery rate. Crossbow hunters using mechanical broadheads recovered 66 out of 69 deer for a 96 percent recovery rate; those using fixed blades recovered 53 out of 65 deer for an 82 percent recovery rate.

Pedersen went so far as to separate fixed-blade recovery rates into pre- and post-mechanical eras. There was no statistically significant difference. Recovery rates with fixed-blade broadheads shot from compound bows were 82.2 percent from 1989 to 2006 and 81.0 percent from 2007 to 2012. For crossbows: 81.7 percent in the early years, 80.0 percent more recently.

A Personal Thing

Choosing a broadhead is a very personal thing. Sometimes the law dictates what you use. For example, Idaho still bans mechanicals for big game hunting, and if you want to hunt Cape buffalo in South Africa, you must use a cut-on-contact two-blade head. If you keep in mind that a broadhead has one function, and one function only–to cut a hole through hair, hide, muscle and internal organs–and that to do so it must be strong enough to withstand some serious abuse and designed so precisely that it can be made to fly like a laser beam, you can now eliminate the cheap stuff and choose from one of dozens of broadheads on today’s markets with confidence that fits your equipment, the game you’re hunting and the conditions under which you’ll be hunting it.–Bob Robb

  1. A hundred years ago (it seems), late 50’s and early 60’s. Fred Bear was my idle!! We had Fred Bear broad heads with inserts and without. We would hand sharpen them again and again. We had Fred Bear camouflage on our face and hands. We even had Fred Bear toilet paper. He was a great marketer!! Anyway, we put our wooden shafts in a pencil sharpener and hot-glued on the heads!!! Of course, it took a couple of brews to get all that equipment ready the night before opening season. Sitting beside a campfire in the Black Hills of South Dakota, hearing the sound of the creek nearby and at about 4,600′ elevation and seeing your breath when stepping away from the campfire………all with the anticipation of the “big One”.
    Enjoyed your article. Dave Olsen

  2. For this study to be conclusive, all hunters would have had to been given an accuracy test on targets using the broadhead they will hunt with. Otherwise it cannot be determined if broadhead accuracy was more of a factor than broadhead performance.

    1. I completely disagree with the statement that you would have to clarify accuracy by the archer. The inherent nature of the sport is that you can’t be completely accurate everytime. All broadheads do the job on perfect shots. The thing to remember is broadheads are about your bad shots not your good ones. Which head does the most damage without sacrificing durability and penetration.

  3. Robb, your article is one of the more accurate summaries of my research study I have read, well done! I have three more years of recovery data since publishing the “A Comparative Study on the Effectiveness of Fixed Blade and Mechanical Broadheads”, and may do another paper or article…

    With respect to Mike’s above comment, all hunters were required to pass a Bowhunter Education course, and pass an annual proficiency test with broadheads on 3-D deer targets. (These requirements (and others) separate out the bowhunters in the Indian Head Study from the general population of bowhunters). The proficiency test was not difficult, but it was at least was able to weed out bowhunters who were “incompetent” or in some cases, stricken with target panic because of “test pressure”. (I was a qualifier in the early years of the program). There was no requirement to hunt with the broadheads with which one passed the proficiency test. The research study focused on deer recovery statistics of hunters who used either a crossbow or compound bow, with either fixed blade or mechanical broadheads. Since over 1000 deer were recovered, I was able to statistically mitigate variables such as hunter experience, bow weight, arrow weight, shot distance, shot angle, deer alertness, etc., etc.

    Clearly the Indian Head Study showed an advantage to using mechanicals regardless of the choice of bow. The Indian Head Study is but one data point on a rather controversial topic, so it is not a final word by any means. That being said, I started bowhunting in 1964 and switched to mechanicals for the first time in 2013 when I realized the implications of this research. (I bowhunt with a compound bow). I will likely never use another fixed blade broadhead on a deer.
