is higher grain ammo better

Posted on: January 8th, 2021 by No Comments

For example, a Hornady 180 grain round nosed.30 caliber bullet has a BC of.239, a Hornady 180 grain spire point bullet has a BC of.431 and a 180 grain Speer boat tail spitzer bullet has a BC of.540. However, they are inexpensive, reliable brands that should be your first choice when selecting ammo for practice or competition. It is also the case that heavier bullets will tend to have higher sectional density than lighter bullets of the same caliber, though it's typically a very small advantage. A lighter projectile travels faster, a heavier projectile has (slightly) more momentum, meaning it's carrying more energy into the target. The 147 and 124 grain are bullet weights. FMJ rounds (left) and 95 gr. So does that mean that heavier-for-caliber bullets work better in the real world? Alien Gear Holsters is bent on crafting the worlds best concealed carry holsters on the planet. It is an extremely small unit. Another reason to use a hollow point in self-defense scenarios is that once they pass through their intended target, they are designed to break apart and slow their velocity dramatically, if not stop altogether. 2020 Alien Gear Holsters. The two attributes people are concerned about when it comes to handgun bullets are penetration and expansion. A heavier bullet travels slower but hits with more momentum, while a lighter bullet has a flatter trajectory and greater velocity. He resides in the great Inland Northwest, with his wife and child. For defensive ammunition, some people go with a heavy-grain hollow point, while others prefer a lighter, faster bullet. Essentially the idea comes down velocity vs momentum. are perfect. Gold Dot 9mm 115 gr. 165-grain vs 180-grain .40 S&W ammo? In fact, 1 ounce is equal to 437.5 grains, just to give you an idea of how small it is.For another comparison, 1 gram is equal to 15.43 grains. I ordered some 95 grain JHP's from them yesterday on a whim. Muzzle Velocity and Down-Range Velocity So a higher grain can be louder, and also have more recoil/kick than a lower grain I have had 9 mm guns that shot 4-5" low at 10 yards, with 115 grain ammo, and shot to point of aim (POA) with 147 grain. In reverse, higher grain size bullets can be a better choice for self-defense. Penetration depth is right in the middle of the zone, great expansion, and … What matters there is placement, and that has nothing to do with grain weight. The topic of self-defense ammunition raises the question of projectile grain weight and the degree to which it matters. Granted, this only works to a degree, so don't get too ahead of yourself. Newer calibers like the 6.5 Creedmoor are designed with more stopping power as well as flatter trajectory than previous rounds were capable of. Anyhow, a 115-gr projectile has a mass of 7.45 grams (0.00745 kilograms) and 1150 feet per second (ballpark velocity for 115-gr 9mm bullets) works out to 350.52 m/s. 9mm bullet weights range from 115 to 147 grains and velocities from 1,200 to 1,000. For example, one ounce is equal to 437.5 grains. In some cases, lighter projectiles penetrated more deeply than heavier projectiles of the same design but expanded to the same degree, such as 124-gr and 147-gr Federal HST. Again, for handgun bullets. Some commercial ammo is loaded to Higher pressures. The main thing that a larger grained bullet means is that it will drop faster than a smaller grain bullet during the trajectory. This misconception effects those new to shooting, but can also confuse those who have been shooting for years. However, if you have the choice between different grains of JHP, the heavier the bullet, the more damage it will do. Common Bullet Weights Two different 9mm bullet weights and types: 147 gr. There are also some practical reasons why it might matter. TulAmmo 9mm Luger Ammo 115 Grain FMJ Steel Case is manufactured by the Tula Cartridge Company, the leader company in Russian ammo manufacturing. Rifles often use a BTHP bullet for better accuracy. The 124 grain bullet loaded to higher pressures (+P) will have a higher velocity than the standard load with a heavier 147 bullet. Heavier bullets are slower and are often subsonic, meaning an even greater noise reduction is achieved if shooting, say, 147-grain 9mm ammunition (already subsonic) or 230-grain.45 ACP ammunition, also subsonic. Now, the conventional wisdom is that a heavier bullet will dump more energy into the target, and penetrate further into soft tissue though (possibly) at the cost of expansion. For example, jacketed hollow point ammunition performs extremely well inside of a live target, while full metal jacket ammunition will not do as well. Speaking of distance shooting, that segues nicely into our next shooting scenario. This is impressive. For hunting and any kind of defense shooting, a larger grain is generally better. In others, such as Remington's HTP loads, penetration was the same but the heavier grain weight didn't expand or didn't expand as well. The bullet reaches a muzzle velocity of about 3,100 fps from a 24-inch barrel and is among the best ammo for self-defense and all-around AR15/M16/M4 ammo. Have a look, for instance, at Lucky Gunner Labs ammunition tests. by Tier1arms | May 13, 2020 | Rifles | 0 comments. 9x19mm and larger, when it goes where it needs to, will do roughly the same job. Where lead-free bullets must be used, the 35-grain Ballistic Silvertip LF in 22-250 Rem. It’s no surprise that heavier bullets drop more quickly during flight, so bullet manufacturers must find a balance between stopping power and bullet trajectory. Heavier bullets are slower and are often subsonic, meaning an even greater noise reduction is achieved if shooting, say, 147-grain 9mm ammunition (already subsonic) or 230-grain .45 ACP ammunition, also subsonic. When loaded into hunting rifles, a heavier bullet is more likely to deliver more energy into the target, resulting in a more humane shot. Lower grain will travel faster when shot but also has less weight pressure (knock down power) and a higher grain will not travel as fast but is has more weight pressure. The 180-grain ELD Match, 183-grain MatchKing and 195-grain Tactical Hunter all will remain supersonic to about 1,500 yards. The quality of the projectile and competent marksmanship make more difference. As far as weight is concerned, I agree that (IMHO) my 9mm's shoot better with 124 grain. However, those practical considerations aside, what are some other considerations when it comes to projectile grain weight? The same 180-grain bullet with a muzzle velocity of 2,450 fps will perform almost identically. Zero at 300 makes for 6-8” low at 400. The grain is the weight, just make sure you note, the higher the grain-the higher the weight of the bullet and most likely higher amount of powder. Sound complicated yet? For more than 100 years, it has served the needs of hunters and sport shooters, law enforcement and even the military. When loaded into hunting rifles, a heavier bullet is more likely to deliver more energy into the target, resulting in a more humane shot. In … But if you use more gunpowder or … The 150-grain ELD-X bullet stayed supersonic past 1,200 yards while the 162-grain ELD Match was supersonic to almost 1,400 yards. The 9mm has the advantage of higher capacity without enlarging a firearm's grip. So, how much does this matter in the real world? The more violent the cycling, the more wear and tear the pistol sustains on the contact parts of the gun, which is why most manufacturers advise limited use of +P ammunition. Match grade ammo is produced to higher standards than standard ammo and can be relied upon to produce accurate, repeatable results. So long as you've selected a quality bullet, and place it where you need it to go, the difference is pretty much academic. For this purpose, bullet grain is not a big factor in your decision. For self-defense, the best ammunition is the hollow point. Does it make a difference if you're carrying 9mm 147-grain or 115-grain? Gun type goes a long way in determining the preferable load. 9mm ammo can be divided into three classes: light, medium power and supersonics and heavyweights. The stuff you take out to the range to blow off a few magazines. Make sure that your gun can properly load, feed, eject and reload the actual ammo that may one day save your life. In fact, the term grain is actually a unit of weight measurement. Also, the portion of recoil that you feel is influenced by the force of the slide going back. make perfect sense for plinking. 9mm bullet weights range from 115 to 147 grains and velocities from 1,200 to 1,000. For short range pure horsepower Barre burning hunting loads, look for the 3500-3700 fps node. Modern handgun ammunition, in the traditional calibers used for defense, tends to be roughly equally effective in the field when accurately placed. For comparison purposes, the higher the number the better the BC and the less air drag the bullet has. The Effects Of A Higher Grain Weight With 9mm Ammunition. Larger grain, heavier bullets, generally perform better inside a target. A 9mm bullet weighing exactly 124 grains. The 9mm has the advantage of higher capacity without enlarging a firearm's grip. The following rounds are FMJ rounds that are not recommended for self-defense except in cases of dire necessity when nothing better comes to hand. ammunition, 55-grain FMJ is far and away the most popular load used by semi-automatic rifle shooters. But keep in mind, that this is situation dependent and there is no definitive yes or no answer. Parse the 9mm ammunition, for instance, and look at when a particular load (same projectile manufacturer, design) that has data for the various grain weights. The case for a lighter weight but faster bullet Those who advocate for a lighter but faster bullet will point to the fact that the formula for kinetic energy is 0.5mv^2 (1/2 of the mass x the square of the velocity); meaning that a lighter bullet at a higher speed will carry more kinetic energy than a heavier bullet at lower speeds. Then there’s range ammunition. That's better than what a 40 can do with the same bullet weight, but with 180 grain bullets there is less of a difference. For example, if other factors are equal, a 150 grain .270 bullet will penetrate better than a 150 grain .35 caliber bullet. Brands differ in "cleanliness", reliability, and price. Depending on the situation, a higher grain may be better for you. For most applications, the heavier the grain, the more stopping power you will have. For this purpose. In other words, a skinny bullet of a given weight tends to penetrate better than a fat bullet of the same weight, because it concentrates the same force on a smaller area of the target. This is especially important for people who shoot a suppressed pistol, and those who prefer a larger caliber than 9mm. Superformance ammo from Hornady stands out for its high muzzle velocity.The ammo is remarkably powerful, and it can squeeze a little bit of extra range out of most guns.It is also accurate, and particularly resistant to wind drift. So in this instance, lighter is better. The 150-grain bullet has a muzzle velocity of 2,820, while the 180-grain has a muzzle velocity of 2,620 feet per second. number comes in at .444 while the AccuBond's is rated much higher at .588. Other people believe that the bigger the wound channel, the more rapid the blood loss and thus incapacitation will be, and thus more reliable expansion is more desirable. Let us also clarify that we are discussing the merits of heavier or lighter grain weights for the same caliber, such as 115 gr vs 147 gr 9mm. Most new shooters assume that the term grain refers to gunpowder, and the number of grains is equal to the amount of gunpowder in a cartridge, i.e., a 55gr 5.56mm FMJ. I have also gone to 147-150 grain for my long barrel handguns. JSP rounds (right). For self defense, a heavier bullet gives you a better chance at stopping a threat. A grain is a unit of measurement for mass. Being that my XD has a 3" barrel, I would rather not use a 147gr as it won't get accelerated very much. That's part of what makes the muzzle rise! Choose A Lighter Bullet Grain If… A smaller bullet can be effective if overall speed and distance is your goal. The best of both worlds...better momentum than a 115gr, and better velocity than a 147gr. Besides, a lighter cartridge can reach long distance than the heavy one, meaning you can shoot the living target without being recognized. The grain is the weight of the bullet. As you can see by these back-of-the-envelope calculations, a heavier-for-caliber projectile has slightly more momentum than a lighter-for-caliber projectile sitting over the same charge of powder. There is a common misconception in shooting sports about what exactly a “grain” is. All Rights Reserved. Born in southeastern Washington State, Sam Hoober graduated in 2011 from Eastern Washington University. More powder is necessary when the bullet is heavier due to the larger mass needing to be moved. Velocity at Muzzle: 888fps Average Penetration: 17.3 ”; Best 9mm Ammo for the Range. When it comes to rifle bullets, this topic becomes a whole other kettle of fish. When it comes to efficacy on a hostile target? For example, you’ll find Federal American Eagle 9mm ammo in, 115 gr., 124 gr., and 147 gr. For instance, most 9mm loads are either 115, 124, or 147 grain, but occasionally you might see a 95 grain, 110 grain, or some other oddball load. The main thing that a larger grained bullet means is that it will drop faster than a smaller grain bullet during the trajectory. If you’re hunting from distances over 300 yards, bullet drop is a real factor. Then there’s range ammunition. 9mm rounds are better with lower bullet grain since they often have a higher muzzle velocity, lower recoil, and are relatively more accurate. Handguns may use a TMJ or JHP bullets so the base is encased for better accuracy. Is higher grain better or is lower better for a pistol - Answered by a verified Firearms Expert We use cookies to give you the best possible experience on our website. A very small unit of weight measurement, in fact. It determines how fast the bullet will travel too. Most people go with the cheapest ammo they can find for range day. I read your article here and I noticed that you're from Washington state. A 147-gr projectile with a velocity of 950 fps (ballpark for 147-gr 9mm) would have momentum of 2.757 kg m/s. Momentum is a simple equation, p=mv. Why? Sectional density - the density of a section of material - is a predictor of a projectile's ability to penetrate through resistance, meaning a heavier bullet has a slightly better propensity - on paper - for penetrating deeper into tissue. There is one additional factor to consider in hunting that doesn’t matter in self-defense, and that is bullet trajectory at long distances. Best 5.56 Ammo For 1/7 Twist: Prior to choosing our 5.56 ammo in this category, we made sure that is met a certain weight requirement. What are Handgun Suppressor Sights and Why Would I Need Them. Okay, so the first part: what you gain and lose with lighter-for-caliber bullets compared to heavy-for-caliber bullets. The Federal 115-grain 9mm ammo has a muzzle velocity of 1,180 fps, while the larger bullet is propelled at 1,000 fps. Action length doesn't matter.
