‘What Does Grain Mean In Ammunition?’ Before we get started we would like to discuss what it is like to be a shooter. The first thing beginner shooters need to do is know the basics like proper gun holds, gun parts,bullet parts and safety. But as you gain experience and go further into the world of shooters you’re likely to inevitably come across some interesting terms such as powder weight, velocity and more…
What Does Grain Mean In Ammunition?
In firearms, grain is simply a word used to describe parts of ammunition. If a shooter tells you something like, “I’m shooting 200-grain .45ACP rounds” or “I have a 185-grain load,” that might confuse you. It can be a bit tricky and dangerous as a novice shooter since you might think that they are talking about their bullet’s powder weight. That’s not entirely true. Because it might differ which powder brand you are using. You need to keep that in mind that brand matters! So the brand you are using might be the definitive answer to ‘ What Does Grain Mean In Ammunition?
Why You Must Be Concerned About Bullet Grain?
If you are an inexperienced shooter, you never have to worry about the grain. All you have to do is make sure that your muscle memory is improving. Don’t hesitate to choose the cheapest ammunition in the beginning. It will work like magic! But if you are constantly changing your ammo, it will also affect your accuracy. You know why? This is because the bullet weight is different.
Here are the factors that bullet weight affects:
Accuracy – If you use a light or heavy bullet there will be many differences in your shooting accuracy such as velocity and bullet drops. According to the law of gravity the heavier the bullet, the faster it drops its trajectory. On the other hand, light bullets also lower the trajectory rapidly. If your bullets are heavy, it’s gravity pulling them down. Also,iIf your bullet is too light, of course, it’s their speed that will pull them down.
Actually, barrel length and rifling twist rate is also affecting the accuracy of the bullet. The heavier the bullet, the more twist rate you need and lighter the bullet, the less twist rate you need. So if you are shooting 5.56 77GR Match ammo , you will want a 1:7 twist rate to give the projectile more stability through flight. If you shoot 55GR 5.56, you can get away with 1:8 or 1:9 twist rate since the bullet is lighter, it not require as much rotation in flight to remain accurate. Temperature, humidity, elevation all play a role in the accuracy of a bullet to include weather or not your rifle is warm from already shooting or if the barrel is cold since metal shrinks the dimensions of the interior of the barrel.
In general, light bullets are generally faster in the muzzle and provide a flatter trajectory.
Velocity And Power –These two things work in coordination with your bullet weight. In short, light bullets move faster and penetrate the target better. However, it will have less impact.
Recoil – Recoil rate is one of the most debated info among the shooting community. The main fact is that if gasses are released slower from the barrel, the less recoil you’ll have.
