Hornady Sub-X rifle bullets in .338 Caliber, 307 grains (Hornady part no. 33394) are built as part of Hornady’s Sub-X line, a heavy-for-caliber expanding bullet designed around subsonic ammunition. This .338-caliber 307gr option gives handloaders working up subsonic loads, often for suppressed rifles, a purpose-built bullet weight instead of adapting a supersonic hunting bullet to a slower load. Packaged 50 to a box, it’s sized for reloaders developing quiet, low-velocity .338-caliber ammunition.
