Vihtavuori expands reloading data with .25 Creedmoor, 9 mm Luger and .357 Magnum

November 13, 2026

Vihtavuori has expanded its reloading data offering with the addition of the .25 Creedmoor (6.53 mm), the first SAAMI-standardized .25 caliber cartridge specifically designed to maximize the performance of modern, sleek, low-drag bullets for superior long-range ballistics and minimal recoil.

At the same time, Vihtavuori is also introducing new reloading data for the popular 9 mm Luger (9×19 mm) and .357 Magnum cartridges, further expanding the available load options for handgun reloaders.

Often described as the “Goldilocks” cartridge of precision shooting, the .25 Creedmoor is created by necking down the 6.5 Creedmoor case to accept .257-inch bullets. It retains compatibility with standard short-action rifles and AICS-pattern magazines through a maximum overall length of 2.800 inches. Originally developed as a popular wildcat cartridge among handloaders, the .25 Creedmoor was officially standardized by SAAMI in January 2025. The standard established key specifications, including a maximum average pressure of 62,000 psi and a reference velocity of 2,810 fps with a 134-grain bullet.

Positioned between 6 mm and 6.5 mm cartridges, the .25 Creedmoor offers a compelling balance of flat trajectories, excellent wind-bucking performance, and moderate recoil. These characteristics make it well suited for precision long-range shooting as well as hunting applications. The .25 Creedmoor reflects the growing demand for modern, high-performance .25 caliber solutions in precision rifle shooting.

For handloaders, the cartridge’s efficient case design pairs exceptionally well with Vihtavuori powders, offering extensive opportunities for load development and performance optimization. With its combination of high ballistic efficiency, reduced wind drift, strong downrange energy retention, and minimal recoil, the .25 Creedmoor is an excellent choice for shooters seeking precision at extended distances.

The new .25 Creedmoor reloading data is now available on the Vihtavuori website and in the free Vihtavuori Reload App. Reloaders can find load data for a broad selection of hunting and target bullets, including Barnes TTSX BT and LRX BT, Hornady CX, Speer BTSP, Berger VLD Hunting, Elite Hunter, and Long Range Hybrid Target, and Cutting Edge MTH, as well as Sierra HPBT MatchKing.

In addition, the latest data update includes new load data for 9 mm Luger (9×19 mm) and .357 Magnum, providing handgun reloaders with even more options for developing accurate and reliable loads with Vihtavuori powders.

As always, new data lines are highlighted in orange for easy identification in both the online Reloading Data database and the Vihtavuori Reload App.
