Today, we will be walking through The Patriot, rifle powder offered by Shooters World Powders. First, we will cover an overview of The Patriot, the rifle that was used for testing, the type of components and reloading gear used for each test, .223 Remington, powder throwing consistency, cleanliness test, and finally, temperature sensitivity.
Overview of The Patriot from Shooters World Powders
The Patriot is a unique propellant; its density is 0.975 grams/cc. It can be loaded with 223 Remington, 5.56MM, 308 Winchester, 7.62MM, 22-250, 6MM Arc, and 6.5 Grendel, among others. The spherical powder has similar uses as H335®, but has the additional value of being flash suppressed, and superior temperature sensitivity.
Rifle Build
The Rifle itself was built by GCP Rifle Co, supported by a Vision Competition chassis, Kauger VPR action, and SAAMI Standard Barrel (24", Twist rate called by SAAMI for the cartridge, and all other associated dimensions). Here, the barrels we use for this testing are nothing special, and what would be seen in a "run of the mill" rifle barrel you would purchase from your LGS. The rifle itself comes in at about 18 pounds total, roughly, with the scope and bipod included.
Reloading equipment
The equipment used for this testing was a L.E. Wilson hand and sizing die for the 223 Remington. The reloading procedures were very basic, nothing fancy. Clean, anneal on the AMP, resize, clean again, chamfer and deburr, prime, powder, seat bullet and away we go. The components for the testing was Starline .223 Remington brass, Ginex primer, and a 55 grain Berger FB target.
The Patriot Powder Test with 223 Remington
For the "load workup," I followed the simplest approach, starting low and working upward, without conducting any “fine-tuning” to present the results at their most basic level. It should be noted not to copy any of my load data. Any difference in components and rifle configurations will give you different results regarding pressure. Please consult the reloading manual and follow safe loading procedures.
223 Remington Test
For the 223 Remington, the charge weights utilized were 23.8, 24.1, 24.4, 24.7, and 25 grains behind a Berger 55 grain FB target seated at 2.292"" COAL.
At 23.8 Grains, we achieved an AVG velocity of 3118 FPS, STDV of 21,8, and an ES of 69.6. The 10-shot group produced a .661 MOA group.
Next, we have 24.1 grains, with an Avg velocity of 3146.7 FPS, and a STDV of 11.9, with an ES of 33.8. The 10-Shout group ES came out to .674 MOA.
24.4 grains, yielded an AVG velocity of 3185.5 FPS, STDV of 12.7, and ES of 37.1. Here, the 10-shot group yielded .569 MOA.
24.7 grains of The Patriot yielded an AVG of 3217.2 FPS, a STDV of 9.6, and ES of 29.4. The 10-shot group came out to be .466 MOA.
25 grains yielded an AVG of 3263.7 FPS, a STDV of 12.2, and an ES of 44.7. With a 10-shot group, producing a .538 MOA group.
How well does The Patriot, rifle powder from Shooters World Meter?
For this test, I used a Harrels Powder Measure to test how consistently the propellant can meter through a volumetric powder thrower. 30 charges were thrown, consequently, and weighed on an A&D FX120I for confirmation. For the 30 samples, the SD reached .02, with a mean of 30.301. This propellant metered extremely well. However, the powder measure also did an exceptional job at throwing to. The highest charge weight was 30.34, and the lowest was 30.26. As a side note for the powder measure, I'd advise using some anti-static for the tube itself. During the first few throws, I noticed some wide variation because some of the kernels were stuck inside the tube.
How clean is The Patriot from Shooters World Powders?
This test is not very scientific, but it will be used as a baseline for future testing. Nonetheless, what I did was weigh individual patches first, applied C4 Boretech to the barrel, then proceeded to dry patch the barrel out and weigh the patches dirty on the A&D FX120I.

How Temp Stable is The Patriot from Shooters World Powders?
The temperature stability test was conducted in our laboratory, with a calibrated conditioning chamber at 125 degrees Fahrenheit, 1.5 hour soak time, with a baseline at 70 degrees Fahrenheit, and also at -40 Degrees shooting a 5.56 with a 69 SMK. It resulted in about 1/2 foot per second change per degree!

The Patriot rifle powder, a versatile ball propellant, excels in many applications. Its design enables precise adjustments via volumetric throwers on progressive presses, streamlining loading. With an optimal burn rate, it supports calibers from 5.56mm to 30-06 Springfield, delivering excellent velocity and temperature stability for high-performance cartridges.
