At GS Custom, we develop custom ammunition for both pistol and rifle calibers for your particular application such as cowboy action shooting, hunting, competitive shooting, etc. We will work with you to understand your application and required performance. The factors include:

• selecting bullet weight and type
• powder load
• overall length
• velocity
• range
• ballistics
• terminal performance

Our processes, procedures, and extremely tight tolerances ensure that we can reliably produce the identified best load (combination of components) for your application in the quantity you need.

We adhere to the SAAMI standards for ammunition manufacturing. The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) is an association of the nation’s leading manufacturers of firearms, ammunition, and components. SAAMI was founded in 1926 at the request of the federal government and tasked with:

• Creating and publishing industry standards for safety, interchangeability, reliability, and quality
• Coordinating technical data
• Promoting safe and responsible firearm use

Our custom ammunition group will create rounds to meet your exact load requirements and OAL using your powder and projectiles. We will make twenty test rounds to your exact specifications for each variation. Our nominal fee includes equipment setup and labor. Call us at (727) 541-2200 to discuss your needs.

New Product Line – Factory New Ammo – Factory Select

We have manufactured a very limited supply, an introductory run, of factory new ammunition. This new Factory Select line is now available only in hollow points in 50-pack boxes. We have the following calibers: .357 Magnum, .41 Magnum, .44 Special, .44 Magnum, and .45 ACP. Depending on customer interest, we will be gearing up to offer the Factory Select line of factory-new ammunition in other pistol calibers and bullet types, such as FMJ.

Custom Ammo –
    It’s In Our Name

In addition to all the commercial remanufactured ammunition we manufacture, we create ammo to our customer’s specifications. If you are a competitor, or hunter, or want to tailor a specific load tuned to a certain firearm, we can make it for you. Although not a common request, a recent client asked us to load .38 caliber shot capsules. These capsules are designed to be filled with small-diameter birdshot, which will act like a “mini-shotgun” for close-range varmint and pest control when shot out of a revolver. Use the Contact Us form or call us at 727-541-2200 to get pricing and production schedule for your custom ammunition.

.50 BMG – Power At Distance

When top-end power and accuracy at hiking distances are required, .50 BMG is the round for you. If you haven’t seen this cartridge up close, it might be difficult to appreciate its size. For comparison, the rounds at the bottom left are .223 Remington. The .50 BMG cartridges were part of a custom ammo order we completed recently. Use the Contact Us form or call us at 727-541-2200 to get pricing and production schedule for your custom ammunition.

In case there is an armed robber hiding behind the heavily stocked cooler at the 7-Eleven in the next town over, this round could be very helpful. ☺

Tribute Shells

Over the last 20 or more years, a few families, who wished to have their loved ones remembered uniquely, have approached us. They requested that we encapsulate a small portion of that loved one’s cremains in a sealed rifle and/or pistol shell, to be given to the family members, as a tribute for and lasting memory of their loved one’s life.

After the recent death of a loved one in military service, a family member requested that we use the empty shells collected by the military honor guard from the 21-gun salute at the very moving graveside service. Although not always possible, we were able to use those shells to complete the project. The family requested that we make these shells into keychains so that they could distribute them to the family members as a memorial and a daily reminder of the service and sacrifice of their military hero.
