Reloading Your Own Ammo - What You Need to Know

Reloading your own ammo has its own pros and cons. Some people do it out of a hobby or to obtain customized rounds for their rifle. Reloading ammunition has its economic and operational benefits, along with some drawbacks.

  • Reloading Saves Money: If you focus on economics, the most pricey part of a round is the brass casing. Almost 50% of the cost is related to the casing, which implies that reloading will save you almost 50% of the money, if not more, than buying a new pack of ammo.
  • Grendel Ammo is Often Scarce: This may sound unbelievable, but the 6.5 Grendel is not mass-produced like most other calibers. You’ll have problems finding the 6.5 Grendel ammo offline, plus it’s not cheap brass. So it is a better option to reload, so you never run out of the 6.5G load.
  • Accuracy and Customization: Filling up your own rounds will let you improve accuracy and customize the loadout by modifying characteristics of the bullet like velocity, length, and weight (grain).
  • For When SHTF: We all know that gun laws are becoming tighter by the day. Be it the 6.5 Grendel or any other caliber, things like restrictive online sales and local laws might make it difficult to procure. So it's always better to have a reloading setup prepared.


  • Time Consuming: Reloading ammunition is not as easy as reloading magazines. It takes time and precision. If you don’t have much time to spare, this is not your cup of tea. Plus, it also has upfront costs involved (like procuring equipment), and you need to have a dedicated space.
  • Requires Precision: You have to be very precise and technically sound to refill your ammunition. If you’re not that knowledgeable, or can’t handle such meticulous procedures, it’s better to stay away from it. Doing it wrongly can, and will, be compromising or even fatal.
  • Restrictive: Self-loaded ammunition is not allowed in most indoor shooting ranges. Be sure to check.

Is All Powder the Same?

Of course, not. Gunpowder differs on parameters such as burn rate and density. Some powders burn faster than the others, so it is essential that you use a reloading guide to get the proper value of the gunpowder weight to be added.

The 6.5 Grendel is a low recoil round with an excellent ballistic coefficient. It generally requires a mid-rate (neither fast nor slow) burning gunpowder to steer the projectile to a higher velocity and a longer distance. For heavier grains, you require slower burning gunpowder to properly burn and propel the projectile to the desired velocity.

Different Granule Shapes (Source)

Another thing to consider is the granule shape which includes flake, ball, and stick. It’s the stick-type powder which dominates the rifle market, and you should choose the same for your 6.5 Grendel.

Another factor to determine when choosing a gunpowder is density. A more dense gunpowder will have more weight and will not require you to fill-up a double charge, which may cause it to spill out while reloading. Not all gunpowders are created equal. Some powders burn twice as fast at just half the weight, compared to other ones. So, properly analyze the weight/amount of powder using the reloading guide.

How We Chose Our Top Picks

For us to claim that we have outlined the top picks, you need to know about the factors we consider while picking these products.

Shelf Life: Gunpowders can be classified into three types. Single base, double base, and triple base, with the shelf life in increasing order respectively. Triple base powders are not relevant here (they are good for navy shells). The powder that is generally used with a shelf life of years is the double base, and all of our picks are of the same type.

Caliber/Burn Rate: The 6.5 Grendel requires a medium burn rate gunpowder for lighter projectiles and a slow burning powder for magnum ones. All the powders in our list have a burn rate appropriate for the 6.5G.

Clean: A good gunpowder must burn clean, leaving little residue/grime behind. All of our picks are far from dirty, but it's still a good practice to clean your rifle regularly.

Good Load Density: Our picks have a good load density to let you fill the optimum amount of powder so the case seals perfectly. With all the powders in our list, it's almost impossible to double charge the 6.5 Grendel case.

Accurate and Versatile: You can use the below-reviewed powders to load 5.56, 7.62, and the 6.5 Grendel rounds. A good reloading powder must be accurate and versatile enough to be used with other calibers.

Price and Availability: The 6.5 Grendel is not so readily available on the renowned shelves. So to reload it, you need to choose a powder which is readily available and inexpensive to solve the economic purpose.
