Sme Sight Rite Bore Sghtr 300/338win

The SME Sight Rite Bore Sighter for 300/338 Winchester is a precision-engineered laser bore sighting tool designed to dramatically reduce the time and ammunition waste associated with zeroing rifle scopes. This caliber-specific bore sighter uses a high-output laser and precision-machined brass casing to align your optics with exceptional accuracy before firing a single round downrange.

Shooting Made Easy manufactures this bore sighter to exacting tolerance specifications, with factory calibration matched specifically to the 300 Winchester Magnum and 338 Winchester Magnum cartridge families. The precision-machined brass casing ensures repeatable laser alignment across multiple uses. Three alkaline button cell batteries are included, providing adequate runtime for multiple sighting sessions. The compact design—measuring 7.25 inches in length and weighing just 0.25 pounds—makes it portable enough to carry in a range bag or truck without adding significant bulk.

This tool is essential for hunters, precision rifle shooters, and tactical users who work with magnum rifle platforms. Whether you're preparing for a long-range hunt, conducting rifle maintenance after barrel changes, or performing post-repair verification, a bore sighter eliminates the guesswork of initial scope alignment. Using a bore sighter before live fire also reduces ammunition consumption during zeroing—a practical advantage when expensive magnum cartridges are involved. The caliber-specific design ensures the laser emerges from the same axis as your ammunition, eliminating the parallax errors common with universal bore sighters.

Bore sighting is a fundamental step in rifle optics work, and selecting the correct caliber-specific tool eliminates variables that can compound into larger point-of-impact shifts. The SME Sight Rite system delivers that precision-matched approach at a practical price point for serious shooters.
