Precision long range is very velocity dependent. Having accurate data on your ammo is a must-have for proper DOPE. All of the ballistic calculators in the world won’t help if your velocity is off to start with. From cheapest to most expensive, here are the chronographs I’ve tested hands-on! 1. Caldwell Ballistic Precision Chronograph Each range session it will be accurate to itself. If one bullet reads 1000 fps and the next one reads 1200 fps, it’s very likely that there was a 200 fps difference between the two. The MagnetoSpeed V3 ballistic chronograph kit was designed to be used on barrels and suppressors from 1/2 inch all the way up to 2 inches in diameter. In addition to the larger diameter tolerance, the V3 also has one inch more clearance in the blast zone to account for longer (up to 3″ in most cases) muzzle brakes, flash hiders, etc.Designed and manufactured in the US, the V3 is a barrel mounted chronograph that uses electromagnetic sensors to determine the velocity of a projectile leaving a rifle barrel when fired. The benefits of a barrel mounted chronograph mean that it’s easy to get an accurate reading of muzzle velocity without the hassle of setting up tripod measuring systems or placing devices down range. The chrono looks at the light above or below two sensors set apart by about a foot and waits for the light to be disturbed. Light on the first sensor is disturbed, and then X milliseconds later the light of the second sensor is disturbed.

Unique 3-piece clamp works with both Arca & Picatinny rails, needing just one slot for installation and 2” of rail space. Two-way adjustment via four stainless steel adjustment rods should provide adequate movement of the bayonet for nearly all rifles. There is NO CANT adjustment of the bayonet, meaning if you have an angled forend or a rail that is not parallel with your barrel, this mount will not work for your rifle.The list goes on. But basically, it’s an advanced user kind of thing. But don’t let that scare you — they’re actually easier to get into than you might think.
