Note: Federal Premium does not publish muzzle velocity, muzzle energy, or ballistic coefficient data for this specific load in publicly available materials at the time of writing. The ballistics table below uses estimated values based on Barnes TSX 150 gr published data from comparable sources and should be treated as calculated estimates only. Community-submitted chronograph data will be incorporated as it becomes available.
Ballistics Table
Calculated estimate. Real-world results vary by barrel length, temperature,altitude, and lot. Community submissions will provide measured muzzlevelocity for comparison.
Zeroed at 100 yards. Sight height: 1.5" above bore. Estimated muzzle velocity: ~2,820 fps (based on Barnes TSX 150 gr .308 Win reference data from comparable loadings).
| Yards | Velocity (fps) | Energy (ft-lbs) | Trajectory (in) |
|---|---|---|---|
| 0 | ~2,820 | ~2,649 | -1.5 |
| 100 | ~2,614 | ~2,277 | 0.0 ← zero |
| 200 | ~2,416 | ~1,945 | +3.5 (estimated) |
| 300 | ~2,226 | ~1,651 | 0.0 (estimated) |
| 400 | ~2,044 | ~1,391 | -14.8 |
| 500 | ~1,870 | ~1,164 | -42.1 |
Note: All values marked with ~ are calculated estimates. Muzzle velocity has not been confirmed by Federal Premium in published documentation. BC used for trajectory calculation is an estimated G1 of approximately 0.430, consistent with Barnes TSX 150 gr bullets in this caliber. Do not use these figures for precision long-range work without chronograph confirmation.
Key takeaway: At typical hunting distances of 100–300 yards, this load retains well over 1,600 ft-lbs of energy — generally considered sufficient for deer-sized game and many larger species. The trajectory remains manageable out to 300 yards with a 100-yard zero, requiring modest holdover corrections. Beyond 400 yards, drop becomes significant and wind drift increases, making field confirmation of actual muzzle velocity important for hunters planning shots at extended range. The Barnes TSX bullet’s design prioritizes penetration and weight retention over a high BC, so this is not optimized for extreme long-range shooting.
The Barnes TSX Bullet
The Barnes TSX (Triple-Shock X) is a solid copper hollow-point bullet with three circumferential grooves machined into the shank. Those grooves reduce bearing surface contact with the bore, which lowers chamber pressure compared to earlier all-copper designs — a meaningful engineering improvement that allowed Barnes to bring lead-free performance into compliance with standard pressure specifications across a wider range of chamberings.
On impact, the hollow-point cavity initiates expansion reliably across a broad velocity range. The all-copper construction means the bullet does not shed a lead core; instead, it expands into four or six uniform petals that remain attached throughout penetration. Independent terminal performance testing and field reports consistently show weight retention above 95%, often near 100%, which translates to deep, straight wound channels. This characteristic makes the TSX particularly well regarded for hunting in jurisdictions where lead-free ammunition is legally required — including California and several other states with condor range restrictions or broader non-toxic mandates.
Federal Premium’s pairing of its own brass casings, carefully inspected Boxer primers, and purpose-formulated propellants with the Barnes TSX is intended to deliver consistent velocity and pressure across temperature ranges — a practical consideration for hunters who may be shooting in cold early-morning conditions far from a bench.
Best Uses
Good fit:
- White-tailed deer, mule deer, and pronghorn at ranges from close timber shots out to approximately 300 yards
- Elk and black bear hunting where deep penetration and high weight retention are prioritized over fragmentation
- Hunting in California or any jurisdiction with lead-free ammunition requirements, where the all-copper TSX construction satisfies non-toxic regulations
- Hunters who want a single load that performs reliably on both deer-sized and larger North American game without changing ammunition
- Any scenario where recovered bullets are expected to be inspected — the TSX’s petal-expansion and weight retention make for clean, documentable terminal performance
Not the right tool for:
- Varmint or predator hunting where rapid fragmentation and minimal meat damage are priorities — the TSX is built to penetrate, not to fragment
- Long-range precision shooting beyond 400 yards, where the moderate BC of the solid copper 150 gr bullet results in meaningful wind sensitivity and drop compared to high-BC match or hunting bullets
- Budget-conscious shooters who need to practice frequently — at over $2.50 per round, this is a premium-priced hunting load, not an economical training option
- Hunters in regions with no lead restrictions who prefer softer-recoiling, lower-pressure alternatives — all-copper bullets can run at slightly higher pressures than comparable lead-core loads in some rifles
Reliability Notes
No structured submissions yet.
Based on manufacturer claims and open-source information: Federal Premium states that primers used in this line undergo dimensional and charge-weight inspections at higher frequency than standard production, with the stated goal of reducing lot-to-lot ignition variation. The propellant formulation is described as matched specifically to Federal’s performance targets for this load, rather than being a generic powder selection.
The Barnes TSX bullet has a long commercial track record dating to its introduction in the early 2000s, and field reports across hunting forums and published tests consistently note reliable expansion at impact velocities above approximately 1,800 fps — relevant for hunters estimating the effective range of this combination. At the estimated muzzle velocity for this loading, that threshold is reached somewhere between 400 and 500 yards under standard conditions, though Federal has not published an official minimum expansion velocity for this specific product.
No reports of feeding or extraction issues specific to this load were identified in open sources at the time of writing. Brass case quality in Federal Premium lines is generally described in open sources as consistent and suitable for single reloading, though this page covers factory ammunition only.

Note: The Barnes VOR-TX 308 Win 150 gr TSX uses the same Barnes TSX projectile as this Federal Premium load. The primary differences are the case, primer, and propellant sourcing. Hunters comparing these two loads should evaluate price per round and availability rather than expecting meaningful terminal performance differences.
Price Reality
- Typical retail range: $48–$55 per box of 20 rounds, based on observed pricing at time of writing; case pricing (typically 10 boxes / 200 rounds) is not consistently available for this load and varies by retailer
- Per-round cost: approximately $2.40–$2.75, with $51.49 per box representing a mid-range observed price point
- Compared to the Barnes VOR-TX 308 Win 150 gr TSX (same bullet, Barnes-assembled): the Federal Premium version typically runs $3–$8 more per box — a modest premium for Federal’s case and primer sourcing
- Compared to Federal Power-Shok 308 Win 150 gr SP: this load costs roughly double per round, reflecting the premium Barnes TSX projectile and enhanced quality-control steps
- Compared to Hornady Precision Hunter 308 Win 178 gr ELD-X: the Federal TSX load is priced similarly or slightly higher, but serves a different purpose — terminal penetration versus higher-BC long-range performance
- Fair price benchmark: $48–$54 per box is a reasonable market price for this load. Prices above $58 per box suggest supply constraints or retailer markup and warrant comparison shopping. Prices below $44 per box are unusual and worth verifying for authenticity and lot condition.

FAQ
Does the Barnes TSX bullet in this load comply with California’s lead-free hunting regulations?Yes. The Barnes TSX is a solid copper projectile with no lead core, which satisfies California’s Ridley’s Law (AB 711) requirement for non-toxic ammunition when hunting with any firearm anywhere in the state. It also meets lead-free requirements in other states and zones that restrict or prohibit lead projectiles for hunting. Hunters should always verify current regulations for their specific zone and season, as rules can change. This is one of the primary reasons hunters choose TSX-loaded ammunition over comparable bonded lead-core options at similar price points.
How does this load compare to the Barnes VOR-TX 308 Win 150 gr TSX, which uses the same bullet?Both loads use the identical Barnes TSX 150 gr projectile, so terminal performance on game should be essentially equivalent assuming similar impact velocities. The differences lie in the case, primer, and propellant — Federal uses its own brass and primers, while Barnes VOR-TX uses its own component selection. In practice, velocity and pressure are expected to be very similar. The Federal Premium version typically costs slightly more per box. The choice between them often comes down to availability and whether a shooter has a brand preference for Federal’s quality-control processes.
What is the effective range of this load for deer-sized game?Based on estimated ballistics for a 150 gr Barnes TSX at approximately 2,820 fps muzzle velocity, the load retains sufficient energy for ethical shots on white-tailed deer out to approximately 400 yards under standard conditions. However, the Barnes TSX is designed to expand reliably above roughly 1,800 fps impact velocity, which occurs at an estimated 450–500 yards for this loading. Most hunters and ballistic references recommend keeping shots within 300–350 yards with this combination to ensure reliable expansion and to maintain practical field accuracy. Federal has not published an official maximum effective range for this product.
Is this ammunition suitable for elk or larger North American game?The Barnes TSX is widely used for elk, black bear, and similar large game, and the 150 gr weight in .308 Winchester is within the accepted range for these species at moderate distances. The all-copper construction and near-100% weight retention provide deep, straight penetration — a key requirement for large, heavy-boned animals. That said, some hunters prefer heavier bullets (165–180 gr) in .308 Win for elk specifically, to maximize sectional density and penetration margin. This 150 gr TSX load is a capable choice for elk within 250–300 yards; hunters planning shots on very large animals at longer ranges may want to evaluate heavier options.
Can the brass cases from this ammunition be reloaded?Yes. Federal Premium uses Boxer-primed brass cases, which are compatible with standard reloading equipment and can accept new primers, powder, and projectiles. However, this page covers factory ammunition only and does not provide reloading data. Hunters who intend to reload should consult published load data from bullet and powder manufacturers for appropriate specifications. The quality of Federal Premium brass is generally regarded in open sources as consistent and suitable for reloading, though case life will depend on chamber dimensions, firing pressure, and resizing practices.
