The .270 Winchester is one of the great American hunting cartridges. Introduced by Winchester in 1925 and championed by outdoor writer Jack O’Connor for decades, the .270 carved out a permanent place in the hunting world by doing one thing exceptionally well: delivering a fast, flat-shooting, moderate-recoil round that handles everything from pronghorn to elk with the right bullet. Nearly a century later, the .270 Winchester remains one of the top-selling rifle cartridges in the country.
This guide covers real ballistic data for five common .270 Winchester factory loads. You will find muzzle velocity and energy figures, gel test performance data, bullet drop charts to 500 yards, comparisons against the .30-06 and 6.5 Creedmoor, and specific hunting load recommendations by game.

1. What Is .270 Winchester?
The .270 Winchester is a necked-down .30-06 Springfield case firing .277-caliber bullets. Winchester introduced it in 1925 alongside the Model 54 bolt-action rifle, and it quickly gained a reputation as a flat-shooting, hard-hitting hunting cartridge with less recoil than the .30-06 it was derived from. The cartridge uses a long-action case (2.540 inches) loaded to a SAAMI maximum average pressure of 65,000 PSI.
The .270 Winchester’s calling card is velocity. A 130-grain bullet at 3,060 fps from a 24-inch barrel delivers a trajectory flat enough to hold on fur at 300 yards with a 200-yard zero. That combination of speed, energy, and shootability made the .270 the default choice for Western big game hunting for most of the 20th century.
Key Specifications
| Specification | Value |
|---|---|
| Parent Case | .30-06 Springfield (necked down) |
| Bullet Diameter | .277 in (7.04mm) |
| Case Length | 2.540 in (64.5mm) |
| Overall Length | 3.340 in (84.8mm) |
| Max Pressure (SAAMI) | 65,000 PSI |
| Rifling Twist | 1:10 (standard) |
| Action Length | Long action |
| Common Bullet Weights | 130gr, 140gr, 150gr |
Takeaway: The .270 Winchester combines .30-06 case capacity with a smaller, faster bullet to produce one of the flattest-shooting standard hunting cartridges available. It has been taking game cleanly for a century.
2. 5 Factory Loads Compared
| Load | Bullet Weight | Bullet Type | MV (fps) | ME (ft-lbs) | G1 BC | Application |
|---|---|---|---|---|---|---|
| Winchester Ballistic Silvertip 130gr | 130gr | Polymer Tip | 3,050 | 2,685 | .433 | Deer / Pronghorn |
| Hornady Precision Hunter 145gr ELD-X | 145gr | ELD-X (expanding) | 2,970 | 2,839 | .536 | Long Range Hunting |
| Federal Premium 150gr Nosler Partition | 150gr | Nosler Partition | 2,830 | 2,667 | .465 | Elk / Large Game |
| Barnes VOR-TX 130gr TTSX | 130gr | TTSX (all-copper) | 3,060 | 2,702 | .420 | Hunting (lead-free) |
| Remington Core-Lokt 130gr PSP | 130gr | Core-Lokt (cup-and-core) | 3,060 | 2,702 | .414 | General Hunting / Budget |
The 130-grain loads cluster tightly at 3,050–3,060 fps — the .270 Winchester’s sweet spot. The Hornady 145gr ELD-X sacrifices roughly 80 fps of muzzle velocity for a dramatically higher BC (.536 vs .433), which means it retains more velocity and energy past 300 yards despite starting slower. This is the modern long-range option.
The 150gr Nosler Partition runs slower at 2,830 fps but carries the most sectional density (.279) and the deepest penetration potential. It is the elk bullet of the group.
Takeaway: For deer inside 300 yards, any 130gr load works. For longer shots, the 145gr ELD-X is the clear choice. For elk and large game, step up to the 150gr Nosler Partition.
3. Terminal Ballistics — Gel Test Results
Gel Test Results — Hunting Loads
| Load | Impact Velocity (fps) | Penetration (in) | Expanded Diameter (in) | Weight Retention (%) | Notes |
|---|---|---|---|---|---|
| Winchester BST 130gr | ~2,960 (25 yds) | 16.5 | .56 | 60% | Rapid expansion; some fragmentation typical of polymer tips at high velocity |
| Hornady 145gr ELD-X | ~2,890 (25 yds) | 21.0 | .51 | 82% | Controlled expansion across wide velocity window; deep penetration |
| Federal 150gr Nosler Partition | ~2,760 (25 yds) | 24.0 | .50 | 68% (front core) | Partition design; front expands, rear drives deep |
| Barnes 130gr TTSX | ~2,970 (25 yds) | 20.0 | .54 | 99% | All-copper; four-petal expansion; near-perfect weight retention |
| Remington 130gr Core-Lokt | ~2,960 (25 yds) | 18.5 | .53 | 65% | Traditional cup-and-core; reliable expansion at moderate depth |
What the Data Shows
The .270 Winchester at full velocity hits hard. The 130gr Winchester BST opens to .56 inches but only retains 60% of its weight — typical fragmentation behavior from fast, thin-jacketed bullets. This is perfectly acceptable for deer-sized game, where rapid expansion and energy dump create quick, ethical kills. It is not the bullet for elk.
The 145gr ELD-X at 21 inches with 82% retention demonstrates why Hornady’s InterLock ring and Heat Shield tip design work: controlled expansion with enough structural integrity to penetrate deep. The 150gr Nosler Partition at 24 inches is the penetration leader — no surprise from a bullet engineered specifically to hold together on heavy game.
The Barnes 130gr TTSX at 99% retention and 20 inches of penetration is the standout for hunters in lead-free jurisdictions. The all-copper construction means zero fragmentation and four uniform petals that create a consistent wound channel.
Takeaway: The .270 Winchester’s gel performance confirms its hunting versatility. Light 130gr bullets expand rapidly for deer. Premium 145–150gr bullets penetrate deep enough for elk. Choose your bullet based on your game.
4. Bullet Drop Charts — 100 to 500 Yards
Bullet Drop Table — 200-Yard Zero (inches)
| Range (yds) | 130gr BST (3,050 fps) | 145gr ELD-X (2,970 fps) | 150gr Partition (2,830 fps) |
|---|---|---|---|
| 100 | +1.5 | +1.6 | +1.8 |
| 200 | 0.0 | 0.0 | 0.0 |
| 300 | -6.2 | -6.5 | -7.5 |
| 400 | -18.0 | -18.8 | -22.0 |
| 500 | -36.5 | -37.8 | -44.5 |
Velocity Remaining at Distance (fps)
| Range (yds) | 130gr BST | 145gr ELD-X | 150gr Partition |
|---|---|---|---|
| Muzzle | 3,050 | 2,970 | 2,830 |
| 200 | 2,678 | 2,696 | 2,523 |
| 300 | 2,501 | 2,561 | 2,379 |
| 400 | 2,332 | 2,430 | 2,240 |
| 500 | 2,171 | 2,304 | 2,106 |
Notice the crossover: the 145gr ELD-X starts 80 fps slower than the 130gr BST but carries more velocity at every distance past 200 yards. By 500 yards, the ELD-X is 133 fps faster than the BST — a direct result of its .536 G1 BC. For any shooting past 300 yards, the ELD-X is the superior choice despite its lower muzzle velocity.
Energy Remaining at Distance (ft-lbs)
| Range (yds) | 130gr BST | 145gr ELD-X | 150gr Partition |
|---|---|---|---|
| Muzzle | 2,685 | 2,839 | 2,667 |
| 200 | 2,071 | 2,341 | 2,120 |
| 300 | 1,806 | 2,112 | 1,884 |
| 400 | 1,569 | 1,901 | 1,670 |
| 500 | 1,360 | 1,710 | 1,476 |
The 145gr ELD-X carries 1,710 ft-lbs at 500 yards — more than enough for deer and approaching the 1,500 ft-lb threshold for elk. The .270 Winchester with modern high-BC bullets is a legitimate 500-yard deer cartridge.
Takeaway: The 130gr BST is flattest inside 300 yards. The 145gr ELD-X carries more energy and velocity past 300 yards. For mixed-range hunting, the ELD-X is the better performer.
5. .270 Winchester vs .30-06 Springfield
The .270 Winchester is literally a .30-06 case necked down from .308 to .277. The parent-child relationship means the two cartridges share similar case capacity, action length, and overall dimensions. The difference is bullet diameter and what that means for velocity and trajectory.
| Metric | .270 Win 130gr | .30-06 150gr | Advantage |
|---|---|---|---|
| Muzzle Velocity | 3,060 fps | 2,910 fps | .270 (+150 fps) |
| Muzzle Energy | 2,702 ft-lbs | 2,820 ft-lbs | .30-06 (+118 ft-lbs) |
| Drop at 400 yds (200 zero) | -18.0 in | -20.5 in | .270 (2.5 in less) |
| Drop at 500 yds | -36.5 in | -42.0 in | .270 (5.5 in less) |
| Recoil (8 lb rifle) | ~17 ft-lbs | ~18.5 ft-lbs | .270 (slightly less) |
| Bullet Weight Range | 130–160gr | 150–220gr | .30-06 (more versatile) |
| Elk Suitability | Adequate (150gr premium) | Excellent (180gr premium) | .30-06 |
The .270 shoots flatter. The .30-06 hits harder and offers a wider bullet weight range for large game. For deer-sized game, the .270 Winchester’s trajectory advantage is a genuine practical benefit at 300+ yards. For elk and moose, the .30-06’s ability to push 180–220 grain bullets gives it real margin the .270 cannot match.
Takeaway: The .270 is the better deer cartridge. The .30-06 is the better elk cartridge. Both handle everything in between.
6. .270 Winchester vs 6.5 Creedmoor
| Metric | .270 Win 145gr ELD-X | 6.5 CM 143gr ELD-X | Advantage |
|---|---|---|---|
| Muzzle Velocity | 2,970 fps | 2,700 fps | .270 (+270 fps) |
| Muzzle Energy | 2,839 ft-lbs | 2,315 ft-lbs | .270 (+524 ft-lbs) |
| G1 BC | .536 | .625 | 6.5 CM (+.089) |
| Drop at 500 yds | -37.8 in | -41.2 in | .270 (3.4 in less) |
| Energy at 500 yds | 1,710 ft-lbs | 1,666 ft-lbs | .270 (+44 ft-lbs) |
| Recoil (8 lb rifle) | ~17 ft-lbs | ~12 ft-lbs | 6.5 CM (30% less) |
| Action Length | Long action | Short action | 6.5 CM (shorter/lighter rifle) |
The .270 Winchester drops less and carries more energy than the 6.5 Creedmoor at every distance to 500 yards. The 6.5 Creedmoor’s higher BC begins to close the gap past 600 yards, but most hunting happens inside 500. The 6.5 Creedmoor wins on recoil (30% less), action length (short vs long), and ammunition variety for competition shooting. The .270 wins on hitting power for hunting.
Takeaway: For hunting, the .270 Winchester hits harder at every practical range. For target shooting and recoil-sensitive shooters, the 6.5 Creedmoor is the better platform.
7. Hunting Load Selection by Game
| Game | Recommended Load | Effective Range | Notes |
|---|---|---|---|
| Pronghorn | 130gr Winchester BST or Hornady SST | 0–450 yds | Flat trajectory for open-country shots |
| Whitetail Deer | 130gr Remington Core-Lokt or Barnes TTSX | 0–400 yds | Core-Lokt for budget; TTSX for lead-free |
| Mule Deer | 145gr Hornady ELD-X | 0–500 yds | Best long-range option for open terrain |
| Elk (broadside) | 150gr Federal Nosler Partition | 0–350 yds | Premium construction for deep penetration on heavy game |
| Black Bear | 150gr Nosler Partition or 130gr Barnes TTSX | 0–300 yds | Bonded or monolithic for heavy bone |
| Lead-Free | 130gr Barnes VOR-TX TTSX | 0–400 yds | All-copper; California condor zone compliant |
The .270 Winchester excels as a deer and pronghorn cartridge. It is adequate for elk with premium 150-grain bullets and careful shot placement, but it does not have the .30-06’s margin with heavy bullets. If elk is your primary target, the .30-06 or a magnum is a better choice. If elk is an occasional opportunity while deer hunting, the .270 with a Nosler Partition will handle it.
Takeaway: The .270 is a near-perfect deer cartridge and a capable elk cartridge with the right bullet. Match your ammo to your game and stay within the cartridge’s effective range.
8. Choosing the Right Load
| Use Case | Best Load | Why |
|---|---|---|
| All-Around Hunting | Hornady 145gr ELD-X | Highest BC, reliable expansion, handles deer and elk |
| Deer (budget) | Remington 130gr Core-Lokt | Proven for decades, affordable, widely available |
| Elk / Large Game | Federal 150gr Nosler Partition | Deepest penetration, bonded/partition construction |
| Pronghorn / Long Range | Winchester 130gr BST or Hornady 145gr ELD-X | BST for flat trajectory; ELD-X for energy at distance |
| Lead-Free | Barnes VOR-TX 130gr TTSX | 99% weight retention, four-petal expansion |
Takeaway: The Hornady 145gr ELD-X is the most versatile single load for the .270 Winchester. If you primarily hunt deer and want to save money, the Remington Core-Lokt has been doing the job for generations.
9. FAQ
Is the .270 Winchester good for elk?
With 150-grain premium bullets (Nosler Partition, Barnes TTSX) and broadside shots inside 350 yards, the .270 Winchester is adequate for elk. It is not a margin-of-error cartridge for elk — if you expect quartering shots or longer distances, consider the .30-06, .300 Win Mag, or 7mm Rem Mag.
What is the effective range of the .270 Winchester?
For deer-sized game, the .270 Winchester is effective to 500 yards with modern high-BC bullets like the 145gr ELD-X. For elk, limit shots to 350 yards or less. For target shooting, the cartridge remains supersonic and accurate to 800+ yards.
Is the .270 Winchester the same as .270 WSM?
No. The .270 WSM (Winchester Short Magnum) is a different cartridge using a shorter, fatter case with higher velocity — approximately 100–150 fps faster than the .270 Winchester with the same bullet weight. The two are not interchangeable.
What twist rate does the .270 Winchester use?
The standard twist rate is 1:10, which stabilizes all factory bullets from 130 to 160 grains. Some newer rifles offer 1:8 twist rates to stabilize heavier, longer bullets with higher BCs.
.270 Winchester vs 7mm-08: which is better?
The .270 Winchester is faster (3,060 vs 2,860 fps with 130–140gr bullets) and hits harder. The 7mm-08 fits in a short-action rifle with less recoil. For hunting performance, the .270 has a clear edge. For a youth or recoil-sensitive shooter, the 7mm-08 is easier to handle.
Is the .270 Winchester dying?
No. The .270 Winchester consistently ranks among the top 10 best-selling rifle cartridges in the United States. While newer cartridges like the 6.5 Creedmoor and 6.5 PRC have taken some market share, the .270 retains a loyal following among hunters who value its proven field performance.
