Let’s Dive into Sightmark Laser Bore Sight, 300 Win Mag, SM39006 – 1 out of 29 models
As an outdoor and tactical gear specialist with over a decade of experience, I’ve seen countless gadgets promising to make sighting-in easier. But few truly deliver on that promise. The Sightmark Laser Bore Sight, 300 Win Mag, SM39006 – 1 out of 29 models, from Sightmark, aims to be different, offering a quick and convenient way to get on target without burning through expensive ammunition. This particular model is designed for the popular .300 Winchester Magnum caliber, a cartridge I use extensively for long-range hunting and precision shooting.
What drew me to this particular boresight was the promise of saving time and money at the range. I was tired of wasting precious rounds just to get my scope roughly zeroed. The thought of a device that could get me close to zero before even firing a shot was incredibly appealing.
Upon unboxing, my initial impression was of a simple, no-frills tool. The weight was negligible, and the construction seemed reasonably solid, although I wouldn’t call it bombproof. Compared to some of the magnetic or externally mounted bore sighters I’ve used, this seemed more straightforward. I’ve previously used a Bushnell bore sighter that clamps onto the barrel, and a magnetic bore sighter from Wheeler. I chose the Sightmark because of its chamber-style design, which I believed would offer better alignment and consistency. I was cautiously optimistic, hoping it would live up to its claims of precision and ease of use.
My first impression was one of cautious optimism. It didn’t scream “high-end”, but it did seem like a practical tool that could potentially save me a lot of frustration.
Real-World Testing: Putting Sightmark Laser Bore Sight, 300 Win Mag, SM39006 – 1 out of 29 models to the Test
First Use Experience
My first test of the Sightmark Laser Bore Sight, 300 Win Mag, SM39006 – 1 out of 29 models took place at my local shooting range. I was setting up my custom .300 Win Mag rifle with a new scope. The weather was clear, with a slight breeze, ideal conditions for testing.
Using the boresight was remarkably simple. I chambered it just like a regular cartridge and observed the red laser dot on my target at 50 yards. Adjusting my scope to align with the laser dot was quick and straightforward. There were no complications.
After making the adjustments based on the laser, I fired a three-shot group. To my surprise, the group was only about 3 inches high and 2 inches to the right of the bullseye. This was significantly closer than I expected for a first attempt.
Extended Use & Reliability
After several weeks of using the Sightmark Laser Bore Sight, 300 Win Mag, SM39006 – 1 out of 29 models, I’ve found it to be a reliable tool for initial scope adjustments. It consistently gets me close to zero, saving time and ammunition. The anodized aluminum construction has held up well, with no noticeable wear and tear despite repeated use.
Cleaning is simple; I just wipe it down with a clean cloth after each use. I have noticed that the battery compartment can sometimes be a little tricky to open.
Compared to my previous experiences with other bore sighters, the Sightmark has been a significant improvement. It’s more accurate than the magnetic models I’ve used. It’s also far less cumbersome than the clamp-on versions. While it’s not a replacement for live fire zeroing, it significantly reduces the amount of time and ammunition required to get on target.
