350 Legend

Every bullet used in the data below were sized to 0.356″, with the exception of Winchester factory bullets which already measured 0.355″. Bullets 0.3575″ and 0.3580″ either prevented the Ruger’s bolt from closing… smart bolt, or they generated enough pressure to blow out primers. None of the bullets sized to 0.356″ showed excessive pressure signs. At some point in time, component manufacturers will offer appropriate bullets for handloaders and this sizing step will not be necessary.

Warning: Bullet selections are specific, and loads are not valid with substitutions of different bullets of the same weight. Variations in bullet length will alter net case capacity, pressure and velocity. Primer selection is specific and primer types are not interchangeable. These are maximum loads in my firearms and may be excessive in others. All loads should be reduced by 5% as a starting point for development where cartridges have greater than 40 grains in capacity and 10% for cartridges with less than 40 grain capacity following safe handloading practices as represented in established mainstream reloading manuals. Presentation of these loads does not constitute a solicitation for their use, nor a recommendation.
