6.5×55 Swedish Mauser Ballistic Data Guide: Velocity Charts, Performance & Load Comparisons

1. What Is 6.5×55 Swedish Mauser?

The 6.5×55 Swedish Mauser (also known as the 6.5×55 SE or 6.5 Swede) is one of the oldest smokeless powder military cartridges still in active sporting use. Adopted jointly by Sweden and Norway in 1894, it was designed for the Swedish Mauser M96 rifle and served as the standard Scandinavian military cartridge until the 1960s. After more than 130 years, it remains one of the finest medium-game hunting cartridges ever designed.

The cartridge uses a rimless case 2.165 inches long with an overall length of 3.150 inches. It requires a standard long-action rifle. The 6.5×55 fires .264-caliber bullets — the same diameter as the 6.5 Creedmoor, .260 Remington, and 6.5 PRC. What sets it apart is the combination of moderate recoil, excellent accuracy, and terminal performance that has made it the European standard for deer and moose hunting in Scandinavia for over a century.

The SAAMI maximum average pressure for the 6.5×55 is relatively low at 46,000 CUP (approximately 51,000 PSI) — a conservative limit set to protect the millions of old military actions still in circulation. In modern rifles rated for higher pressures, handloaders can safely push the 6.5×55 well beyond SAAMI specs, approaching .260 Remington performance. CIP (the European pressure standard) allows 55,100 PSI, reflecting the cartridge’s actual capabilities in modern rifles.

The takeaway: The 6.5×55 Swedish is the original 6.5mm — the cartridge that proved the bore diameter’s exceptional combination of high BC, deep penetration, and mild recoil. It predates the 6.5 Creedmoor by over a century and remains a superb hunting cartridge.

2. Factory Load Ballistic Data — Complete Table

Factory loads are loaded to SAAMI pressure limits, which are conservative. All velocity figures are from 24-inch test barrels unless noted.

The takeaway: Factory 6.5×55 loads run 2,559-2,812 fps depending on bullet weight, producing 2,100-2,325 ft-lbs of muzzle energy. These numbers are at SAAMI pressures — handloaders in modern rifles can add 100-200 fps safely. The Hornady 140-grain SST stands out for combining high velocity with a .520 BC.

3. Load-by-Load Performance Breakdown

Hornady 140gr SST

The best hunting load available for the 6.5×55 in terms of combined velocity and BC. The Super Shock Tip is a polymer-tipped boat tail that delivers rapid expansion and devastating energy transfer on deer-sized game. At 2,735 fps with a .520 BC, it produces the flattest trajectory and best energy retention of any factory 6.5×55 load. The InterLock ring prevents jacket-core separation for reliable weight retention. For whitetail and European roe deer, this is the standard by which other 6.5×55 loads are measured.

Federal 140gr Fusion

Federal’s electrochemically bonded Fusion at 2,650 fps is the budget-friendly bonded option. The jacket is fused directly to the lead core at the molecular level, providing better weight retention on impact than traditional cup-and-core designs. This makes the Fusion a better choice than the SST for larger game (mule deer, black bear) where you need penetration through heavy bone. The trade-off is a lower BC (.435) and 85 fps less velocity than the Hornady SST.

Norma 156gr Oryx

The 156-grain Norma Oryx is a Scandinavian hunting standard. This bonded bullet at 2,559 fps was designed specifically for the moose and red stag hunting that the 6.5×55 is famous for in Scandinavia. The Oryx uses a chemical bond between jacket and core that maintains bullet integrity through the heavy bone and dense muscle of large-bodied game. Weight retention typically runs 85-90%. If you are taking your 6.5×55 after anything larger than whitetail, the 156-grain Oryx is the factory load with the deepest pedigree in the field.

PPU 139gr Soft Point BT

PPU offers the most affordable factory 6.5×55 ammunition. The 139-grain soft point boat tail at 2,660 fps is a standard hunting load that performs well on deer-sized game inside 250 yards. The .405 BC is adequate but not outstanding. For hunters who need affordable practice ammo that doubles as a capable deer load, PPU delivers reliable performance at the lowest price point.

Lapua 136gr Scenar-L Match

Lapua’s Scenar-L at 2,690 fps is the precision shooter’s choice. The .556 BC is excellent, and Lapua’s reputation for extreme consistency makes this the most accurate factory load available in 6.5×55. This is a target bullet, not a hunting bullet — but for competition shooters who run 6.5×55 in vintage military rifle matches or F-class, the Scenar-L is the load to beat.

Norma 120gr TipStrike

The fastest factory 6.5×55 load at 2,812 fps, the TipStrike uses a polymer tip and a proprietary core design that creates massive energy dump on light-bodied game. The 120-grain weight at this velocity produces explosive terminal performance on deer and roe deer — rapid expansion and large wound channels that put game down quickly. For hunters who pursue medium game under 200 pounds at moderate ranges, the TipStrike offers dramatic terminal performance.

The takeaway: The Hornady 140-grain SST is the best all-around hunting load. For larger game, the Norma 156-grain Oryx is the proven Scandinavian choice. For affordable practice and hunting, PPU offers the best value.

4. Bullet Drop Charts — 100 to 500 Yards

All drop figures based on a 200-yard zero from a 24-inch barrel at sea level.

The takeaway: With a 200-yard zero, the 6.5×55 drops 7.0-8.2 inches at 300 yards depending on load. Not as flat as the 6.5 Creedmoor or .260 Remington, but perfectly manageable for hunting inside 400 yards. The 140-grain SST’s high BC gives it the best trajectory despite not being the fastest load.

5. Barrel Length & Velocity Considerations

The original Swedish M96 military rifle used a 29.1-inch barrel. Modern sporting rifles typically ship with 22-24 inch barrels, and the velocity loss from the shorter barrel is significant.

The 6.5×55 was designed for a 29-inch barrel, and it shows — the cartridge loses about 23 fps per inch. A modern 22-inch sporter is giving up roughly 175 fps compared to the original military barrel. If you shoot a surplus M96 Mauser with its full-length barrel, you will see velocities closer to modern .260 Remington performance from factory ammunition.

The takeaway: A 24-inch barrel is the recommended minimum for the 6.5×55. If you shoot a full-length military Mauser, your velocities will exceed factory data by 100+ fps. Going to 22 inches is acceptable for hunting but costs meaningful performance.

6. The Pressure Question — SAAMI vs CIP

The 6.5×55 Swedish has a unique pressure situation that every owner should understand. SAAMI lists the maximum average pressure at 46,000 CUP (approximately 51,000 PSI) — conservative because millions of military M96 and M38 Mausers from 1896-1945 are still in circulation. These old actions were designed for pressures around 45,000 PSI and may have metallurgical variations after a century of service.

CIP (Commission Internationale Permanente), the European pressure standard, allows 55,100 PSI for the 6.5×55 — about 8% higher than SAAMI. European-manufactured ammunition from Norma, Lapua, and RWS is typically loaded to CIP specs, which is why European loads often show higher velocities than American-loaded ammunition.

For handloaders, the distinction is critical. In a modern rifle from Tikka, Sako, Ruger, CZ, or similar manufacturers, the 6.5×55 can be safely loaded to 55,000-58,000 PSI levels, approaching .260 Remington performance. In a vintage M96 or M38 Mauser, loads must stay at or below SAAMI levels. When in doubt, have your rifle inspected by a qualified gunsmith before loading above SAAMI pressure.

The takeaway: In modern rifles, the 6.5×55 is a 2,800+ fps cartridge with 140-grain bullets. In vintage military Mausers, stay at or below SAAMI-spec factory loads. Know your rifle before you push the pressure envelope.

7. 6.5×55 Swedish vs 6.5 Creedmoor

Both fire the same .264 caliber bullets. The performance gap depends entirely on what rifle you are shooting.

At SAAMI pressures with factory ammunition, the 6.5 Creedmoor matches or slightly outperforms the 6.5×55. But in a modern rifle with handloads, the 6.5×55’s larger case capacity gives it a 50-100 fps edge over the Creedmoor. The Creedmoor’s advantages are entirely practical: short-action rifles are lighter and cycle faster, ammo availability is vastly superior, and the higher SAAMI pressure means factory ammo fully exploits the cartridge’s potential without handloading.

The takeaway: If you already own a 6.5×55 rifle, handloading unlocks performance that matches or exceeds the 6.5 Creedmoor. If you are buying new, the Creedmoor makes more sense due to market support. Ballistically, these are nearly identical cartridges in different packaging.

8. 6.5×55 Swedish vs .260 Remington

The .260 Remington is essentially a short-action version of the 6.5×55 concept — a .308-family case necked to .264 caliber. With factory ammunition, the .260 Remington runs 2,700-2,750 fps with 140-grain bullets, slightly outperforming the 6.5×55’s SAAMI-limited factory loads. The .260 fits in a short action, giving it a weight and handling advantage.

The 6.5×55 counters with more case capacity (57 vs 53.5 grains of water), which gives handloaders 50-100 fps more velocity at equivalent pressures. The 6.5×55 also has the advantage of European ammunition support — Norma, Lapua, RWS, and Sellier & Bellot all produce excellent 6.5×55 loads that may not be available in .260 Remington.

In practice, these two cartridges produce virtually identical results on game. The choice between them is determined by whether you want a short-action or long-action rifle, and which has better ammo availability in your area.

The takeaway: Same bullets, similar velocities, identical terminal performance on game. The .260 fits in a lighter short-action rifle. The 6.5×55 has more potential for handloaders and better European ammo support.

9. Hunting Performance — 127 Years of Proven Results

The 6.5×55 Swedish has killed more Scandinavian moose than any other cartridge in history. It has also taken countless red deer, roe deer, reindeer, chamois, and wild boar across Europe. In North America, it is equally effective on whitetail, mule deer, pronghorn, and black bear.

The 6.5×55’s secret weapon is the sectional density of 6.5mm bullets. A 140-grain .264 bullet has a sectional density of .287, which means it penetrates deeper relative to its weight than wider-diameter bullets of the same mass. This is why the 6.5×55 has been successfully used on Scandinavian moose (which can weigh 1,000+ pounds) despite generating relatively modest energy — the bullets simply go deep enough to reach vitals from challenging angles.

The takeaway: The 6.5×55 Swedish is a proven game-getter on everything from roe deer to moose. Its reputation for punching above its weight class is earned through 130 years of field results across two continents.

10. Choosing the Right 6.5×55 Load

The 6.5×55 Swedish enjoys good ammo support from both American and European manufacturers. Hornady, Federal, PPU, Norma, Lapua, Sellier & Bellot, and RWS all produce commercial loads. European brands (Norma, Lapua) are often loaded to CIP pressure specs, which run slightly higher than SAAMI — verify your rifle is rated for CIP-level loads before using European ammunition in a vintage military action. Stock up at Tatted Tacticals for the best selection of 6.5×55 Swedish ammunition.

The takeaway: The Hornady 140-grain SST is the best all-around choice for American hunters. For larger game or European-style driven hunts, the Norma 156-grain Oryx is the traditional Scandinavian choice. Always verify your rifle’s pressure rating before selecting ammunition.

11. FAQ

Is the 6.5×55 Swedish still a good hunting cartridge?

Absolutely. The 6.5×55 delivers the same terminal performance it always has — moderate recoil, deep penetration, and effective killing power on deer-class game to 400 yards. Modern premium bullets have actually improved its performance compared to what was available 30 years ago. In a modern rifle with handloads, it matches the 6.5 Creedmoor and .260 Remington ballistically.

Can I shoot hot loads in my surplus M96 Mauser?

No. Surplus M96 and M38 Swedish Mausers were designed for pressures around 45,000 PSI. Factory ammunition loaded to SAAMI specs (51,000 PSI) is safe. Loads above SAAMI pressure — including some European-manufactured ammunition loaded to CIP specs — should only be used in modern rifles verified to handle higher pressures. When in doubt, stick with American-manufactured factory ammunition in surplus rifles.

Why is the 6.5×55 popular for moose hunting?

Scandinavian hunters have used the 6.5×55 on moose for over a century because the high sectional density of 6.5mm bullets provides deep, reliable penetration on large-bodied game. The moderate recoil also allows more precise shot placement — a critical factor on moose drives where shots may be quick and at awkward angles. With 156-grain bonded bullets, the 6.5×55 reliably reaches vitals on broadside and quartering moose shots inside 200 yards.

What rifles are chambered in 6.5×55 today?

New production rifles include models from Tikka (T3x), Sako, CZ, Howa, and Ruger. Surplus Swedish M96 and M38 Mausers are widely available on the used market and are among the finest military bolt-action rifles ever made. Custom builders frequently chamber 6.5×55 on Mauser 98 and Remington 700 actions.

Is the 6.5×55 Swedish obsolete?

Not at all. The 6.5×55 is ballistically competitive with the 6.5 Creedmoor and .260 Remington, fires the same high-BC bullets, and has over 130 years of proven field performance. What it lacks is market momentum — fewer new rifles and factory loads compared to the Creedmoor. But the cartridge itself is not obsolete, and modern ammunition makes it more effective than ever.

Is 6.5×55 ammo expensive?

Prices vary widely. PPU and S&B loads are among the most affordable centerfire rifle ammunition available. Premium European loads from Norma and Lapua run higher — comparable to premium .308 Winchester or .270 Winchester ammunition. For handloaders, .264 bullets are abundant and affordable thanks to the 6.5 Creedmoor’s popularity, and 6.5×55 brass is available from Lapua, Norma, and PPU.
