I don’t know if I would call myself a big-bore guy; I like ‘em small, too. Perhaps “centerfire guy” is more representative of my affinity for larger cartridges of all shapes and sizes, for a multitude of tasks, from personal defense to precision long-range shooting—admittedly, I don’t even spend much time in the .300 Magnum arena although I’ve built a few and am now madly in love with Hornady’s .300 PRC cartridge.
As a gun writer, running the gamut on centerfire cartridges does not come without challenges. Ammo is expensive when you spend quality time on the trigger, especially with new firearms. Out of the box, I spend quite a bit of time sighting-in, seasoning, gathering ballistic and rifle data, and running rigs through whatever paces I feel they are capable achieving, near or far; as an example, not long ago I took a Lead Star Arms Barrage 9mm Carbine to task at 300 yards, then 400, achieving a 5-inch group at 300 and scoring impacts with 3/5 shots on a 3-MOA steel gong at 400—certainly not the norm but the type of work I subject firearms to when reviewing.
This type of work doesn’t happen within just a box or two of ammo. To be honest, my work generally requires a couple hundred testing rounds, sometimes exponentially more if I’m really working to achieve true performance results, pushing limits and yes, battling environmental conditions like high winds. Either way, with a lot of lead heading downrange, I can ill afford to blow ammo on incidental tasks like getting on paper and dialing in optics. For initial shots, I depend on true view-through-the-barrel boresighting and optic adjustment and then move immediately into a laser boresighting device.
To be honest, I do occasionally skip the physical look down the barrel and go straight for the laser boresight, depending on time, whether I’ve used the optic on similar rigs and my environment. What do I mean by environment? Sometimes I try to “jump the gun,” so to speak, on range preparation. I’ve been known to install the optic in my home the night before and use a laser boresight on a target across the house—remember, boresighting (and shooting) at 25 yards generally gets you close at 100 yards—the same can be said for 50 yards and 200. If I can achieve a 25-yard boresight the night before, I’m generally on paper with first shots at 100.
One of Us is Not Like Most
While the juice is generally worth the squeeze as a gun writer, in terms of expenses, every expense definitely cuts into my ability to make a living doing what I love. To that end, using less materials to complete a project means greater profit—this is Business 101. Of course, I don’t cut corners either. So, saving on ammo, cleaning and maintenance materials, etc. makes both good sense… and cents!
And although I do write about shooting and firearms, most folks do not. There is no profit to be made, only expenses and shooting, whether testing, plinking, hunting or going extreme distances, can be expensive. Of course, expensive is subjective, too. Some might say .22 LR plinking is expensive while others aren’t deterred by the cost of .338 Lapua (and more expensive ammo—take a gander at .50-cal BMG and what is costs to run Cheytac and Tejas cartridges).
At the end of the day, for the vast majority of hardworking folks, expensive is clearly defined when it comes to one cartridge or another, and volume of shooting and I have yet to meet a fan of simply wasting ammo they paid for with cold hard cash. Yes, pretty much EVERYBODY likes to keep costs low. If for nothing else, boresighting reigns supreme when it comes to keeping your shots productive. After all, it doesn’t matter who you are, taking shots with no calls and no splash is no fun, even downright maddening.
Laser Boresights: A Journey
So, what’s the buzz on laser boresights? Looking back at my earliest experiences, the first boresights I used were barrel mounted and troublesome to say the least, even at the high-end of costs. Back then, you-get-what-you-pay-for was still frustrating. Soon after I dabbled in barrel-inserted laser boresights. With a tapered bore rod, these boresights were effectively universal; however, I also fought poor construction—expecting the laser to be installed straight and at center-mass was too tall an order. On the flip side, I also worked with some inexpensive fly-by-night models that seemed to perform well.
Now, years later, I’ve been using in-chamber boresights with great success. Among my personal boresights are Firefield and Sightmark, with Sightmark being the premium option. While in-chamber boresights are caliber specific, many cases are certainly similar enough to cover more than one cartridge with a single in-chamber boresight model—cases in point are .22-250 and 6.5 Creedmoor, as well as .243 Winchester and .308 Winchester, to list a couple.
In-chamber boresights have certainly changed the sight-in landscape for those who have elected to employ them, and certainly, as a total have saved shooters a jaw-dropping wad of cash—there’s no question. With a daytime visibility beyond 25 yards, these boresights are sure to get you dialed in close to center-mass and still close to the mark at a 100 sight-in, as explained earlier.
In lower light, if your optic can take it, boresights can certainly stretch out quite a bit farther, say to 50 yards, to close in on that 200-yard zero—100- or 200-yard zero is more or less subjective and one or the other can certainly be beneficial in terms of precision accuracy, depending on factors like load, target distance, etc.
Although Sightmark in-chamber laser boresights have built a solid reputation for accuracy, as evidenced in first-round impacts countless times for shooters at every experience level, there is always room for improvement. As a point of interest here, in-chamber boresight battery life has been a bone of contention for many a shooter. Batteries die at inopportune times and can be cost-prohibitive to an annoying fault. Also worthy of mention, depending on your surroundings, fresh batteries may not be the easiest to find. Of course, there’s a light at the end of the Sightmark tunnel and it’s worth talking about.
Accudot Boresights: Sight-in and Save More
The Sightmark Accudot Laser Boresight System, unveiled at the 2019 SHOT Show, was introduced with problem-solving in mind. While the Accudot holds fast to Sightmark’s precision-machined brass case and premium internal components, the device’s internal rechargeable Lithium-Ion battery is definitely a buzzworthy game-changer. In a device where battery life is notoriously short (and batteries are always more expensive than they should be), eliminating the need for replacement batteries is sure to amount to significant savings—for many, the savings are certain to result in recapturing the cost the Accudot entirely.
Even better, since battery life is still battery life even in a rechargeable system, the Accudot features an auto-activation, meaning the laser only activates while the boresight is chambered. One last notable feature is the Accudot’s calibrated diode. The diode ensures precise laser accuracy and doubles up on Sightmark’s boresight commitment to helping people achieve first-shot impacts on paper. No matter how the numbers work out—ammo or batteries—the Accudot’s aim is simply to save you time and money; for some of us, those two words are all too often one in the same.
