All Available Calibers of Steinel Ammunition

We manufacture calibers within three product families: Vintage Military, Hunting, and Self-Defense.  After quickly moving from 9mm FMJ, we enjoyed almost immediate success with our 44 Magnum and 44 Special loads.  The former were powerful 240 grain coated lead and JHPs.  The latter used a modest charge with a 200 grain bullet.  Energy and bullet design allowed for the FBI-recommended penetration in ballistic gel, but recoil was manageable.

Shortly after delving into 44 Magnum and Special, we began researching, testing, and tweaking what would be our first 308 Winchester and 45/70 Government loads.  We began loading 45/70 to level II power, but quickly learned that there was a large community of shooters that were more interested in light recoil loads for their Trapdoor Springfields.  Others found such loads (in the 20,000 PSI range) more pleasant to shoot- even in guns that could handle a steady die of more than twice that pressure.

The first unusual caliber that we began offering was 7.7 Japanese Arisaka (click for our 7.7 Arisaka product page).  Type 99 Arisaka rifles are not widely known among the shooting community at large, but many individuals interested in WW2 history or military surplus rifles are very familiar with this venerable action.  The proliferation of training rifles (click for example of training rifle) not designed to handle the pressures of standard, centerfire rifle ammunition caused a bit of unnecessary concern among those unfamiliar with these Type 99s.  True Type 99 battle rifles, designed for combat, chambered in 7.7 Japanese Arisaka are among the strongest actions in existence.  We continue to make 7.7 Arisaka today and use this experience to identify other vintage military calibers which have dedicated shooters looking for a reliable source of ammunition for their historic pieces of military history.

The next caliber that we began loading was 458 SOCOM.  Over the last 4 years the popularity of this round has began to soar- along with the number of request for premium projectiles.  In addition to a budget-friendly 300 JHP, we offer these other (458 SOCOM) options.
