.22 Hornet (Somchem Data)

The .22 Hornet remains a unique and charming cartridge, offering excellent velocity and flat shooting performance in a compact package. As seen in Somchem's reloading data, a variety of propellants can be paired with light bullets to create efficient and accurate small game or varmint loads. This data focuses on three primary powders from Somchem’s line: S265, S321, and S335. Each delivers distinct burn rates and pressure characteristics, offering reloaders a flexible range depending on performance goals.

Using a 45 grain PMP SP (soft point) bullet as the standard, the S265 powder shows excellent promise, especially for those prioritizing moderate pressures and consistent velocities. Starting at 9.5 grains and topping out at 11.2 grains, S265 yields velocities ranging from 2,112 fps to 2,521 fps. This powder's controlled burn rate provides steady pressure development and makes it a solid pick for general-purpose shooting.

S321, with a slightly faster burn, offers higher velocities at slightly reduced powder charges. Its data spans from 9.0 grains (2,233 fps) to 10.3 grains (2,546 fps), showing its capability to push the 45 grain bullet with efficiency. Ideal for varmint hunting where velocity and precision are key, S321 offers excellent case fill and reliable ignition characteristics, especially in cooler environments.

For those seeking maximum velocity within safe limits, S335 becomes the top contender. With charge weights ranging from 10.5 to 11.6 grains, this powder pushes the .22 Hornet into the upper limits of its potential, reaching velocities from 2,246 fps to 2,637 fps. While pressures are higher, S335 remains within safe operating ranges for firearms rated for modern Hornet loadings, making it suitable for well-built rifles with strong actions.

Somchem’s data provides essential guidance for safe reloading, and users are always encouraged to begin at the minimum loads and work up cautiously while watching for pressure signs. The .22 Hornet is a forgiving cartridge, but its small case capacity makes it sensitive to overcharges. Proper priming, consistent brass prep, and careful metering are key to getting the most from these loads.

As always, consult the most recent load manuals and follow best reloading practices. These Somchem loads provide a balanced range of options for both casual shooters and serious handloaders looking to get the best from their .22 Hornet rifles.
