![]() Your power-to-weight ratio wouldn’t be sufficient to move the trailer. Think of it like this: you wouldn’t drive a semi to work every day, nor would you hook up a sub-compact car to a trailer to haul it. The weight gives the bullet its capability to penetrate the target. Well, light bullets at high velocities will still lack the penetration of heavier bullets moving at medium velocities. Why Does AR 15 Caliber Weight and Velocity Matter? This is what causes round penetration, and for both hunting or defense, maximum penetration should be your main thought. If you’re not, suffice it to say that velocity means motion: the bullet moving through the gap between you and a target.īullet weight ( also called grain or gr, is a unit of measurement) is the ‘transmission’ of the car engine it’s what gives the round the ability to move (achieve velocity). If you’re into math, you can research numbers like the kinetic energy of around. Yeah, I’m not getting math involved here, though velocity can accompany some scary mathematical equations. Caliber Velocity and Weight Chart Projectiles Velocity is equivalent to the specification of an object’s speed and direction of motion.”Ĭonsider these velocities and weights. Velocity is defined as: “ an object is the rate of change of its position with respect to a frame of reference. It’s what gives the bullet the ability to move. ![]() Think of velocity as the engine of a car. Though these factors are different, they’re still similar, and one affects the other. The power of a cartridge depends upon two main factors: velocity and penetration. AR 15 Caliber PowerĮveryone knows bigger cartridges are more powerful, right? Not necessarily. You should also consider the flexibility and availability of rounds (the 5.56, is the most common AR 15 caliber, is readily available). There are three basic categories to think about when choosing cartridges for your AR 15 and these three usually involve some compromises between power, cost, and usefulness. ![]() It can make you look like an idiot, never mind the damage to your bank account, if you don’t choose the right AR 15 calibers for the job.īut, what’s the difference between the different cartridges for the AR-15? ![]() Making the choice to upgrade your AR has consequences and can affect lives in the real world.
