You can ask what grain arrow and broadhead should I use? This is not only you; it is a common question among most of the hunter’s hunters.

Grain broadhead plays a crucial role in archery performance. A right grain broadhead is very important for bowhunting. An inaccurate broadhead can lead to erratic arrow flight and impact overall archery performance. The grain broadhead must need to match the spine ratings. So, what grain broadhead for 400 spine arrow?

What Grain Broadhead For 400 Spine Arrow

In short,

the grain broadhead for a 400 spine arrow depends on your draw weight, draw length, arrow length, point weight, and types of broadheads. Most hunters use 100-grain broadheads. A heavier broadhead is suitable for higher draw weight and for better penetration. Match the factors with your specific bow setup to find the right spine.

This isn’t everything. To find the correct grain for 400 spines and its impact on archery performance, read this article. So, Let’s dive into deep-

So, What Grain Broadhead For 400 Spine Arrow? 

The grain broadhead for 400 spine arrows depends on various factors, including draw length, draw weight, arrow lengths, point weight, and type of broadhead. As a general guide, most archers think that a 100-grain broadhead weight is suitable because they have the most options and the best arrow speed.

The standard combination for an arrow with 400 spines is a 100-grain broadhead. But if you have a higher draw weight(over 55 pounds), you can also use a 125-grain broadhead. A heavier broadhead leads to better arrow penetration and provides an effective kill.

What Grain Broadhead For 400 Spine Arrow

Some archers recommended adding weight to the front of their arrow by using different arrow components rather than switching to a heavier broadhead because this helps to improve the front-of-center balance of the arrow. Resulting in better arrow flight and accuracy.

However, for your 400 spines, to find the right grain broadhead, you should test with different combinations and see what works best with your specific bow and shooting style.

So, what grain broadhead for a 340 arrow? You should use a 340-spine arrow rather than a 400-spine arrow if you intend to use a heavier broadhead, such as a 150-grain or 175-grain broadhead.

If you are a beginner, seek guidance from expert archers.For 400 spine arrow 60 pound bow and if your bow is a recurve bow ,you should use a 100 to 125 grain broadhead.

Here is a chart to find the right grain broadhead for your 400 spine arrow.

For example,if your arrow length is 31 inches then for 400 spine arrows draw weight should be 29 to 30 inches.

What Grain Arrow And Broadhead Should I Use?

Selecting the appropriate grain broadhead and pulling back weight go hand in hand. It takes longer to go from point A to point B with a heavier arrow. Therefore, the best option for shooters weighing less than 55 pounds is to use a lower grain (100gr) broadhead, as this will increase arrow speed and penetration. For shooters with higher draw weight, 125-grain broadheads offer superior penetration, but if the arrow doesn’t travel from the starting point to the finishing point, you risk doing more harm than good.

Because so many options are available, I typically recommend a 100-grain broadhead when choosing the best broadhead grain. Many options are available for the 100-grain head, ranging from fixed-blade broadheads like Grim Reaper and Slick Trick to mechanical broadheads like Rage. These broadheads work well for both short-range and long-range bowhunting tasks.

Because there aren’t many options for adding weight to the front of your arrow setup, it’s becoming more and more common to add different arrow components instead of switching to heavier heads. Whatever you decide, it’s critical to remember that your field points and broadheads should have the exact grain.

What Grain Arrow And Broadhead Should I Use

Now, what grain arrow should I use? There are several things to consider when selecting the best grain arrows for deer hunting. The amount of kinetic energy an arrow produces—required for a clean kill—depends on size and weight. Deer hunters should generally use an arrow weighing 400 grains or more. Using arrows with a grain weight of at least 5 grains per pound of your bow’s draw weight is a common rule of thumb. 

On the other hand, you want to aim for six to eight grains per pound of draw weight when hunting. A heavier arrow will produce more kinetic energy and be more effective for a clean kill. 

You can think about what grain broadhead for recurve. The choice of broadhead grain for a recurve bow depends on the bow’s draw weight and the arrow spine. A 125-grain broadhead is a popular choice for recurve bows. For a  400 spine arrow 70 pound bow, your arrow length should be 25 inches for a compound bow.

However, ensuring that the arrow spine is appropriate for the bow setup is essential. If the arrow is too weak, it can wobble and stray off-course, while an over-spined arrow can lose energy and velocity as it veers off-target.

What Poundage Is A 400 Spine Arrow Good For?

An arrow’s spine indicates how stiff it is and is usually linked to a particular range of draw weights. A 400-spine arrow is made to perform best with draw weights between a specific range of bows.

The recommended draw weight range for a 400-spine arrow is usually between 40 and 60 pounds. However, a 400 spine arrow for a 60 pound bow is more efficient. This indicates that the arrow is designed to flex appropriately when shot from a bow with a draw weight in this range. For optimum performance and arrow flight, matching the arrow spine to your bow’s specifications is critical.

What Poundage Is A 400 Spine Arrow Good For

However, the arrow’s spine is referenced by the numbers. The different spines indicate the stiffness. An arrow with 400 spines is typically used for 40–60-pound bows. For roughly 55–75 lb bows, a 350 spine arrow is used for approximately 30–50 lb bows and a 500 spine arrow.

A query can be raised in mind: Is a 400-grain arrow good for deer? The weight and size of the arrow are critical considerations when deer hunting. Deer hunters should use an arrow weighing at least 400 grains, advises precision outdoors. The arrow’s weight will dictate how much kinetic energy it releases, which is required for a clean kill.

The standard combination for an arrow with 400 spines is a 100-grain broadhead. Alternatively, a 125-grain insert broadhead can be employed. You should use a 340-spine arrow rather than a 400-spine arrow if you intend to use a heavier broadhead, such as a 150-grain or 175-grain broadhead.

You can think about 400 spine arrows for a 70 pound bow. Using a 400 spine arrow when shooting a 70-pound bow might not be the best idea. For a 70-pound bow with a 29-inch draw length and an arrow length of 28.25 inches, a 400 spine arrow is too weak. It implies you will be safer and have improved arrow flight and penetration with a stiffer spine.

How Heavy Of A Broadhead Should I Use?

Experts in the field advise using 100-gram broadheads for carbon and lightweight aluminium shafts and 125-gram heads for heavy aluminium shafts. 

The bulk of broadheads found in stores have a grain weight of 100. They have a monopoly on the market. And it makes sense since bowhunters want their 100 grainers. Consequently, that’s what stores sell and what the major broadhead manufacturers make and promote. So, always follow the arrow manufacturer guide.

How Heavy Of A Broadhead Should I Use

A 100-grain broadhead is suitable for its various options and proper arrow flight in the general guide. A 100-grain broadhead is ideal for target shooting and as a hunting arrow. You should use a heavier broadhead if you want to go for large game hunting. A heavier broadhead can lead to more kinetic energy and better penetration. It results in an ethical kill of the animal, reducing the animal’s unnecessary.

However, the grain weight of the broadhead depends on your shooting style and personal preferences. Be aware of your safety concerns. An excessively heavy arrows broadhead can lead to erratic arrow flight and be dangerous.

What Happens If The Broadhead Is Too Heavy For The Arrow Spine?

When using a heavy broadhead under spined arrows, the arrow will usually strike to the right. As one increases the weight of their broadhead, they frequently need an arrow shaft with a stronger static spine because increasing point weight weakens the shaft’s dynamic spine. 

Premium shafts tend to group more loosely than lower-grade arrows, and a heavier (or lighter) broadhead may seem more forgiving. Arrow stiffness, or lack of it, could be the issue if you notice that your arrows are dispersed after you’ve examined your form, technique, and equipment. 

How Do I Balance Speed And Accuracy?

You must select the appropriate arrow spine for your bow setup to balance speed and accuracy. The stiffness of an arrow is measured by its arrow spine. The arrow becomes stiffer the lower the number. Your accuracy and consistency will both increase with the proper arrow spine.

The right arrow spine can be found using an arrow spine chart. To find the suitable arrow stiffness, you must consider your draw weight, draw length, and arrow length.

A good choice for maximum arrow speed is lower fletching. As they quickly straighten, the arrows will fly more straight toward the target. But the arrow velocity will reduce more.

You know that accuracy is the main concern in all cases, so you may consider greater fletchings. They will increase the forgiveness of the arrow and help to stabilise while in flight.

Remember that improving shot consistency and accuracy requires a strong right arrow spine. In the bow shop, locate the right arrow spine for your setup.
