Wounding Estimates Span 4% to 50%: Where Shot Angle Fits

Bowhunting studies produce different wounding percentages because their tallies and denominators differ. In Oklahoma, 50% describes bucks struck with traditional bows but left unrecovered, using 22 struck bucks as the base. Maryland's 18% describes unrecovered deer at the 24-hour mark among 908 deer struck by bowhunters who passed testing. Minnesota's range of 4% to 7% describes survey respondents reporting that they wounded a deer. Hunters control their shot angle, and Texas hunter education puts a broadside presentation at the top.

During 1995 to 1997 in Oklahoma, hunters whose weapons were exclusively recurve bows and longbows shot 22 bucks from a group of 80 fitted with radio collars. They retrieved 11. The researchers labeled the unrecovered share a 50% wounding rate, dividing bucks shot but unrecovered by the 22 that were shot. Tracking by radio revealed the fate of the 11 that hunters did not retrieve. Flesh wounds around the shoulder or back left 8 alive; abdominal injuries killed 3 that were never located. Those deaths account for 14% of struck bucks, measuring something different from the widely repeated percentage.

Maryland's research covered 1989 to 2006. All 104 bowhunters had passed both a bowhunter course and an annual shooting test. Using compounds and crossbows, they struck 908 deer, with 162 still unrecovered at the 24-hour deadline. Under the researchers' definition, finding a deer on day two still places it in the wounded category. The resulting 18% therefore does not measure deaths. To estimate losses around 6% of struck deer, they applied survival assumptions drawn from two studies using collars. That makes the 6% estimate dependent on an assumption. A rate of 13% applied to hunters who had taken more than 20 deer; each of the two lower-harvest groups recorded 24%. Differences in equipment, participants and location also separate these bow studies. Their deer-based percentages cannot be substituted for one another.

For its 2025 legislative report, Minnesota mailed a survey to a sample of deer hunters, asking whether they shot and wounded any deer during 2024. Four percent of hunters using crossbows exclusively answered yes, as did 7% using vertical bows exclusively and 2% using firearms. These percentages describe people. The agency cautions that some hunters may report less wounding than occurred because others can view it negatively.

A 1993 South Carolina study provides an observation near the bottom of the range. Twenty-two archers with prior experience shot 61 deer while hunting over feeders. Of those deer, 90% were shot from 10 to 18 meters, and a trained dog tracked every deer that did not fall within sight. One deer remained unrecovered at the 24-hour deadline, producing 1.6% across the 61. Short shots, a controlled hunt and dog assistance define that observation. It does not establish the lowest possible wounding rate for bows.

According to the Maryland researchers, older estimates of 50% fail to account for advances in broadheads, arrows, sights and bows. Traditional bows were the equipment used in Oklahoma. In Maryland's own compound-versus-crossbow comparison, both recorded 18%, but the crossbow portion included just five hunters and 60 deer. Weapon use has also shifted. Minnesota reports that crossbows accounted for 43.8% of archery deer during 2023, followed by 48.2% during 2024. Counting Minnesota's registrations for 2025, we found 14,939 crossbow deer among 29,777 taken with bows, a share of 50.2%. A comparable increase appears in our Kentucky analysis of the crossbow rise.

A separate rifle project by South Carolina's DNR used a large sample. At a coastal hunting club, Ruth and fellow researchers tracked the distance traveled by 493 deer that were killed. Roughly half fell where they were hit. Among those that ran, average distance varied with bullet placement.

That ranking relates organs to distances traveled after bullet hits; arrows were outside the rifle study. Still, two details from the bow sources agree with it. Abdominal injuries killed Oklahoma's three bucks that hunters never recovered, while Texas cautions that deer hit in the gut can cover considerable ground. The shoulder column shows a 3-yard mean after rifle hits, which offers no prediction for arrows. Ruth attributes that result to bullet damage affecting the brachial plexus, the shoulder's nerve bundle. Texas, meanwhile, advises bowhunters against shooting through shoulder bone. An arrow's access to organs changes with angle. In its hunter-education guidance, Texas Parks and Wildlife advises waiting for a better presentation when the deer offers a poor angle.

Within the 61-deer sample, 5 of 33 deer shot broadside (15%) traveled more than 91 meters after being hit. Among deer shot at any other angle, 8 of 25 (32%) traveled beyond that distance. Thus, the angle comparison includes 58 out of 61 deer. Although the article reports a P value of 0.044, calculations from its counts produce approximately 0.13 using chi-square and 0.20 using Fisher's exact test. Chance could account for the distance difference in a sample this small. We treat it as a clue rather than an established finding. Comparing shot placements revealed a larger difference in the same small sample: 7 of 43 deer with vital hits (16%) traveled beyond that distance, compared with 7 of 17 deer with non-vital hits (41%). That comparison also has few deer behind it, with a Fisher P near 0.09.

Following a hit, Texas hunter education recommends a minimum wait of 30 minutes, extending to an hour, before taking up the trail. Pushing a deer sooner can send it several hundred yards. The Medway researchers waited an hour before releasing dogs. By the 24-hour deadline, they had recovered 60 out of 61 deer; trail work after release averaged 30 minutes. Ruth's rifle researchers used distance, available sign and habitat to place deer in four recovery-difficulty classes. Class 2 contained 155 deer that traveled little and provided good sign, with a mean distance of 46 yards. Class 3 held 61 deer that traveled farther with scant or absent sign, averaging 83. For the 24 considered impossible to recover without dog assistance, the average was 152. Since distance helped determine the classes, their separation partly reflects the classification itself. Regardless of the hunter's assessment, every shot prompted dog tracking in that study. Ruth attributes 15 to 20% of harvested deer to a trained dog's work, among them 19 wounded deer still alive.

Our search located no research comparing recovery with either the distance hunters followed a trail before calling or the amount of blood present where the deer was hit. The advice here therefore reflects our judgment rather than a research finding. After waiting, if the hit location provides scant or absent sign, mark the final sign, withdraw and contact a tracker wherever that is legal. This paper included no review of state laws governing tracking dogs. Check with your state's wildlife agency before placing that call.

Each percentage reflects its own location, time period and counting approach. Applying it elsewhere or to a different season is not automatic. Angle-scoring bow research here involved 61 deer, experienced archers, feeders and close shots. The rifle project's measurements concern bullets rather than arrows. Minnesota relies on hunters' own reports from those who elected to respond. Our equipment totals come from registrations, showing what hunters checked in rather than their preferences.

Before a wounding percentage tells you much, its denominator must be clear. Anyone citing one should identify the equipment, the participating hunters and the population used for division. When shooting yourself, follow hunter education's angle guidance and hold off until the deer presents that angle. The limited bow research evaluating angle supports the same direction, but it leaves the question unresolved.
