Key Takeaways
- The .308 Winchester is effective on whitetail and feral hogs from 35 yards out to 400 yards with the right load.
- Hunting with the .308 in North Texas spans tight timber shots under 100 yards and open pasture shots well past 300 yards.
- Bullet weight and construction matter more than velocity at ranges beyond 250 yards on big game.
- Zeroing your rifle at a local range before season opens is the single most important accuracy step you can take.
- AR-platform .308 uppers give you a familiar manual of arms with enough energy for any legal Texas game animal.
Grayson County puts hunters in two completely different situations on the same lease. One morning you are watching a creek bottom in the post oak timber, and the shot is 40 yards. The next afternoon you are glassing an agricultural flat near Pottsboro that opens to 350 yards with nothing between you and the deer. The .308 Winchester handles both. That versatility keeps the cartridge relevant year after year.
Below, we cover effective range by species, grain weight matched to game size, and zeroing resources near Denison before season opens. No filler. Concrete numbers you can act on. If you need a platform to run these loads through, we offer complete .308 Win uppers built to order for compatible lowers.
Why the .308 Winchester Remains a Go-To Hunting Cartridge
The .308 Winchester remains a top hunting cartridge because it delivers roughly 2,600 ft-lbs or more of muzzle energy with common 150 to 180 grain factory ammo you can find at nearly every sporting goods counter in the region. It has been putting deer on the ground since 1952, and newer cartridges have not displaced it for the ranges most hunters actually shoot. It still covers more real-world hunting situations than most hunters will ever need.
Cartridge Specs That Matter in the Field
The .308 Win fires a .308-inch diameter bullet, typically in the 150 to 180 grain range. Muzzle velocity runs 2,600 to 2,850 fps depending on your load and barrel length. A typical 150gr factory load produces roughly 2,600 to 2,700 ft-lbs of muzzle energy, depending on velocity. That is enough to cleanly take whitetail, feral hog, and most North American big game at practical field distances.
Free recoil in a 9-lb rifle typically runs roughly 12 to 17 ft-lbs, depending on the load. That is manageable from a shooting bench, a blind, or a field position. Hunters who shoot from improvised rests in the brushy draws around Hagerman National Wildlife Refuge will appreciate that the .308 does not punish them for a follow-up shot.
How .308 Compares to 6.5 Creedmoor for Hunting
At 300 yards, a typical 150gr .308 hunting load still carries roughly 1,600 ft-lbs or more, and exact figures vary by load, so check the manufacturer's ballistic data. The 6.5 Creedmoor has a higher ballistic coefficient and a flatter trajectory past 400 yards, and it drifts less in crosswind at distance. The tradeoff is bullet weight and frontal area, where the .308 holds an edge on heavier game inside 400 yards.
For Grayson County hunting, where most shots fall inside 400 yards across open pasture or tight timber, the .308 is a practical, proven choice. The 6.5 Creedmoor is a fine cartridge, but the .308 covers the same ground with wider load availability and no real tradeoff at the ranges most hunters actually shoot.
Effective .308 Hunting Ranges by Game Species
The .308 Winchester covers more game species at more distances than almost any other cartridge you can chamber in an AR-platform rifle. But effective range is not a single number. It changes by animal size, bullet construction, and the terrain you are hunting. Here is how the math works out by species.
Whitetail Deer: 35 to 400 Yards
Most whitetail shots on the timbered creek bottoms around Bells and Sherman happen inside 150 yards. The .308 handles those timber shots and open-pasture shots equally well. A typical 150gr hunting load still carries more than 1,000 ft-lbs at 400 yards, a common rule-of-thumb minimum for deer-sized game.
The effective range for deer with a .308 extends to 400 yards in the hands of a shooter who has confirmed their zero and knows their drop. At close range inside 100 yards, bullet construction matters more than ballistic coefficient. A bonded or controlled-expansion bullet prevents blow-through on creek-bottom shots where the angle is steep and the distance is short.
Coyote and Predator Control: 50 to 400 Yards
Coyote control is a year-round job for landowners protecting livestock and managing fawn recruitment across the county. The .308 is heavier than a dedicated varmint round, but it works well when you want reach and a rifle you already carry for deer. A lighter 150gr load or a soft-point ballistic-tip anchors coyotes cleanly out to 300 yards and beyond.
If you want to preserve hides, keep to a heavier bonded bullet that expands more predictably and reduces exit-side damage. Because there is no closed season on coyotes on private land, a dedicated .308 upper pays off across the calendar.
Feral Hog: Close-Range Brush Shots to 300 Yards
Feral hog control is a year-round reality for landowners in this region, with no closed season and no bag limit on private land. Hogs present a different problem than deer. Their shoulder shield is dense cartilage and bone. You need penetration, not just energy. Use 165 to 180gr bonded or solid-copper bullets. They hold together on impact and reach the vitals through that shield.
A 16-inch barrel .308 upper handles dense brush scenarios well. The shorter profile is easier to move through cedar and post oak without sacrificing meaningful velocity at the distances where hogs are typically shot. Browse our .308 Win complete uppers if you are building a dedicated hog rifle.
Larger North American Game: Elk and Black Bear
The .308 is legal on elk and black bear, but it sits at the lower end of recommended power for both. If you use it, choose a premium bonded load in the heavier bullet weights. Shot placement is not optional at that margin. Keep shots inside 300 yards, pick a bonded or partition-style bullet, and put it through the shoulder or directly behind it. The cartridge can do the job. It leaves you no room for a marginal hit.
.308 Grain Weight and Load Selection by Game Type
Grain weight changes what your .308 Winchester does at the target. Pick the wrong load for the game you are chasing and you will get poor expansion on a hog's shoulder shield or over-penetration on a whitetail at 80 yards. Here is how to match your load to the animal.
150gr Loads
The 150gr is the most common .308 hunting load on the shelf, and for good reason. Factory loads are commonly rated around 2,800 fps from a 24-inch test barrel (less from shorter barrels). It shoots flat and performs reliably on whitetail and mule deer inside 400 yards. Bonded or soft-point construction, such as Federal Power-Shok or Hornady SST, expands at .308 velocities without blowing apart. Avoid frangible or varmint-style 150gr loads on deer. They are not built for the penetration you need.
165gr Loads
The 165gr is the practical answer for hunters chasing whitetail and hogs on the same property in the same outing. You get better penetration through a hog's thick shoulder shield than a 150gr delivers, without giving up enough velocity to hurt your trajectory inside 300 yards. If you only want to stock one load, this is the one to start with for mixed-bag hunting in the Cross Timbers country.
175gr and 180gr Loads
Match-grade 175gr bullets like the Sierra MatchKing are not designed for hunting expansion. They are built for accuracy, not terminal performance. For hunting at this weight, use bonded or partition-style bullets: Nosler Partition or Federal Trophy Bonded are the right choices for elk, black bear, and large hogs where deep penetration through heavy bone matters.
The 180gr is the maximum-penetration option. Its lower velocity compared with lighter loads limits your effective range. It earns its place on elk and black bear where you need that extra mass driving through bone. To match one of these loads to the right upper, see our complete .308 Win uppers.
.308 Ammo Selection Table
| Grain Weight | Recommended Game | Effective Range | Notes |
|---|---|---|---|
| 150gr | Whitetail, mule deer | Up to 400 yards | Use bonded or soft-point only; avoid frangible |
| 165gr | Whitetail, hogs, mixed bag | Up to 300 yards | Best all-around grain selection for local mixed-bag hunters |
| 175gr (hunting) | Elk, black bear, large hogs | Up to 300 yards | Nosler Partition or Federal Trophy Bonded; not Sierra MatchKing |
| 180gr | Elk, black bear | Up to 300 yards | Maximum penetration; velocity loss limits range |
Where to Zero Your .308 Near Denison, TX
Why Zeroing Distance Matters
Denison sits in a corridor where the terrain shifts fast. One stand puts you in post oak timber with 60-yard shots. The next field edges bottomland with 300-yard crossings. That mix makes your zero distance a real decision, not a formality.
With a 100-yard zero, drop at 200 and 300 yards varies by load, barrel length, and shooting conditions. Check the load manufacturer's ballistic data and confirm your actual point of impact at the range. Trajectory matters on a whitetail's vital zone. A 200-yard zero can be a useful starting point, but confirm your load's trajectory and point-blank range at the range before relying on it in the field.
If you plan to shoot past 300 yards on open pasture or Red River bottom fields, a confirmed 200-yard or 300-yard zero paired with a printed ballistic chart for your specific load is the only reliable approach. Guessing at that distance costs you deer.
Shooting Ranges and Facilities Near Denison
Hunters near Denison commonly use outdoor rifle ranges along the US-75 corridor, including public and membership facilities that offer 100-yard and 200-yard bays. Verify current hours and range rules before you drive out, since availability and access change seasonally and some facilities require membership or advance scheduling. If a longer bay is needed to confirm a 300-yard zero, call ahead to confirm the distance is open that day.

Season opens soon. Order early so your built-to-order upper can be assembled, headspaced, and function-checked before it ships, leaving time to confirm your zero before opening morning. Call (888) 706-0633 with questions about upper selection.
Choosing the Right .308 Upper or Barrel for Hunting
Barrel length is the most consequential hardware decision in a .308 hunting build. A 16-inch barrel commonly gives up roughly 25 to 35 fps per inch compared to a 20-inch barrel, so expect roughly 100 to 140 fps less from the same load. Check the load manufacturer's data and chronograph your own rifle for exact numbers. For most deer-sized game inside 300 yards, that gap does not change terminal performance enough to matter. Past 300 yards in open pasture, the velocity difference starts affecting drop and retained energy in ways you will feel at the target.
Barrel Length and Its Effect on Performance
A hunter working tight brush in the morning and open pasture in the afternoon faces a real trade-off. A 16-inch barrel is easier to carry through cover and faster to shoulder in close quarters. A 20-inch barrel recovers meaningful velocity for those longer field shots. A 24-inch barrel maximizes velocity but adds weight and length that most hunters find impractical by midday.
If your shots are consistently inside 200 yards, the 16-inch is the practical choice. If you are regularly stretching past 300 yards on open ground, step up to a 20-inch. Our complete .308 Win uppers are assembled, headspaced, and function-checked in-house, ready to drop onto a compatible AR-10 pattern lower.
Gas System Considerations for a Hunting Build
AR-10 pattern .308 rifles typically run a rifle-length or mid-length gas system. Rifle-length gas systems spread the pressure curve over a longer dwell time, which reduces bolt velocity and softens felt recoil. That matters when you are shooting from field positions without a muzzle brake, especially on follow-up shots at moving game.
A mid-length gas system on a 16-inch .308 barrel can run reliably but requires careful attention to gas port sizing and buffer weight. If you want a predictable, low-recoil system for the field, rifle-length gas on a 20-inch barrel is the straightforward path. Gas port location also affects cycling behavior, so confirm the barrel and gas system specifications before choosing a setup.
.308 Hunting in North Texas: Local Conditions and Season Considerations
Terrain and Shot Distance Expectations Near Denison
Hunters in the Cross Timbers ecoregion deal with two very different shot scenarios, sometimes on the same property. Post oak and blackjack oak canopy cuts sight lines down to 35 to 100 yards in timber. Step out onto an open pasture or an agricultural field along a creek drainage and that distance opens to 300 to 400 yards.
A .308 zeroed at 200 yards handles both without any holdover adjustment inside 250 yards. You are not giving up anything in tight timber, and you have more than enough reach for open-field shots on whitetail or feral hogs. That flexibility is one reason the cartridge fits this part of the state so well. If you are comparing build options, review our .308 barrels before choosing an upper.
Texas Deer Season Dates and Legal Caliber Requirements
There is no minimum centerfire caliber requirement for deer in this state. Your .308 is legal, and so is anything larger or smaller in the centerfire class. Whitetail season dates are set annually by Parks and Wildlife. Always verify current dates at tpwd.texas.gov before your first hunt of the year.
Feral hog hunting rules can change, so verify current Texas Parks and Wildlife regulations before hunting. For landowners managing hog populations in the area, the .308 becomes a year-round tool. It is one of the more practical reasons to have a dedicated complete .308 Win upper ready to go. If you have questions about building out a hunting-specific platform, contact our team online.
Frequently Asked Questions
What is the maximum effective range for deer with a .308?
Most experienced hunters draw the line at 400 yards. A typical 150gr hunting load still carries more than 1,000 ft-lbs at that distance, which is enough for clean kills on whitetail with good shot placement. Beyond 300 yards, wind drift and shooter error become the limiting factors, not the cartridge.
What grain bullet should I use for whitetail?
A 150gr soft-point or polymer-tip load works well inside 400 yards on whitetail. If you are hunting hogs and deer in the same outing, step up to a 165gr bonded load. It handles both without requiring a zero change.
Is a 16-inch barrel adequate for deer hunting?
Yes, inside 300 yards. Expect roughly 100 to 140 fps less velocity than a 20-inch barrel, depending on the load. That difference does not meaningfully affect terminal performance at typical hunting distances. Our complete AR uppers are available in multiple barrel lengths if you want to compare options before committing.
Can I hunt feral hogs in Texas with a .308?
It is well-suited for the job. Use a 165 to 180gr bonded or hard-cast bullet for penetration through the shoulder shield. On private land across Grayson County and surrounding areas, there is no closed season and no bag limit on feral hogs.
How does .308 compare to 6.5 Creedmoor past 400 yards?
6.5 Creedmoor carries a higher ballistic coefficient and drifts less in wind at extended distances. For most field shots under 400 yards, the practical difference is small. Inside that range, the heavier .308 bullet holds an edge on larger game.
Where can I zero my .308 near Denison, TX?
Outdoor rifle ranges along the US-75 corridor offer suitable bays for 100 to 300 yard zeros. Verify hours before you go. Call us at (888) 706-0633 for help comparing upper options before your range session.
