Alliant sport pistol burn rate
Competitive shooters of all kinds, from precision to action, benefit from a reliable and clean-burning propellant. These requirements are met by the New Alliant Powder® Sport Pistol TM, which has extremely reliable cycling, excellent charging and box filling, and versatile ballistics. In addition to being optimized for polymer-coated bullets, the Sport Pistol low-muzzle-flash formulation can dissolve polymer coatings on the base of the bullet during the ignition process, unlike comparable powders.

Recently released Sport Pistol Powder from Alliant is suitable for use with a wide variety of common pistol calibers and bullet types, satisfying the two most important requirements of sport shooting: cleanliness and adaptability.
Alliant Powder’s communications coordinator, Jared Hinton, has this to say about their Sport Pistol: “a double-base flake propellant with a low nitroglycerine content.” Essentially, Sport Pistol would overlap with American Select on the burn rate chart. While temperature sensitivity varies widely between uses, Sport Pistol is remarkably stable with a mildly negative slope. “Over a temperature range of -150 to +125 degrees Fahrenheit, it varied by less than 15 fps in our most thorough testing.”
The chemical makeup of the Sport Pistol makes it less likely that polymer coatings on coated lead bullets will be dissolved during use. It also has a low flash and burning temperature. U.S. labor was used to produce this.
Sport Pistol has a bulk density of 10.6 grains/cc, or 0.69 g/cc.The resulting powder is somewhat voluminous, making it ideal for use as a case filler. This powder is useful in the following calibers: 9mm Luger, 9mm Luger +P,.40 S&W,.45 ACP,.45 ACP +P,.38 Special,.357 Magnum,.44 Special,.44 Magnum,.45 Colt, and.44 Magnum.In 9mm Luger,.38 Super,.40 S&W, and.45 ACP, I fired 70 different handloads.In my RCBS Uniflow powder measure,
it weighed charges with a standard deviation of 0.1 grain or less, so the metering was very precise and reliable. If you look at the accompanying chart, you’ll see that, with the exception of the.38 Super, I’ve included the five most accurate loads for each caliber. I only tried three different loads in that caliber, but they’re all included.
Compared to other powders, which are usually slower at the same pressure, Sport Pistol in the 9mm Luger won’t produce speeds that are especially fast, but they will be in the same range as common factory ammunition.

My 9mm Luger with fast-burning powder from a 5.0-inch barrel produced velocities of 1,150-1,250 fps with a 115-grain bullet, 1,050-1,150 fps with a 124- or 125-grain bullet, and 900-1,000 fps with a 147-grain bullet when firing a sporter pistol. The velocity of the heavier bullets ranged from 800 to 900 feet per second.
The fact that accuracy varied by bullet type was par for the course. A few groups of 15 shots were under 1.50 inches, with Rocky Mountain Reloading’s 124-grain FMJ FP producing the tightest group at 1.40 inches. While the +P load did tend to result in a slightly larger group, this was not always the case, and the difference in group size was often small enough to be negligible.
Using the information provided by Alliant for the 9mm Luger, I loaded some.38 Super with a Sport Pistol. I wasn’t looking for a high-velocity load; I just wanted to see what kind of accuracy a low-velocity one would give me. The three bullets I had available for testing shot in groups no bigger than 1.50 inches. If you use the right powder, these three bullets tend to shoot in tight groups, which is why I chose them. It would appear that Sport Pistol is one of the “right” powders.
Use extreme caution when working with any load data. Before moving on to the high-test loads, make sure the lower loads are reliable in each of your firearms. Neither Shooting Times nor the various firearms and component manufacturers take any responsibility for the use of this information because we have no control over your choice of components, guns, or actual loadings.
After 15 shots, the.38 Super load had the tightest group.Even though the 125-grain HAP load only travels at 1,012 fps, the resulting 0.8-inch group is quite respectable.
While my.40 S&W barrel is an inch longer than Alliant’s test barrel, the velocities were very close to those reported by Alliant. However, 135-grain bullets reached speeds of nearly 1,300 fps, which was slightly higher than Alliant’s speed, and 180-grain bullets reached speeds of around 1,000 fps.
With my pistol, the.40 S&W ammunition performed about as well as I had hoped.My 9mm and.45 pistols outperform my.40 S&W.Only two sets measured less than 2.0 inches. However, groups were only slightly larger on average than in 9 mm and.45 ACP, indicating that all three calibers have the same accuracy potential.
Despite only loading a few +P loads for the.45 ACP, I experimented with a few different primers to see if any of them improved velocity or reduced group size.The speeds I measured were very similar to those reported by Alliant. The speeds I achieved are not directly comparable to those of Alliant because I did not always load to the maximum charge weight. When loaded to near its maximum charge weight, the Alliant achieves speeds that are typical for its caliber. Bullets of 230 grains travel at 850 to 900 feet per second, while those of 185 grains travel at 1,000 feet per second or faster. I’m hitting at velocities consistent with those estimates.

Accuracy was found to be linked to bullet type, just like it was with the other calibers. Even though some lead bullets perform admirably, jacketed bullets perform best in my.45 ACP barrel.Very respectable accuracy was achieved with this pistol, with several 15-shot groups measuring 2 inches or less.
When using a 5.0-grain load and Hornady 230-grain HAP bullets, I found that the velocity produced by the Sport Pistol varied depending on the primer used. There was a 52 fps gap between the slowest velocity (produced by CCI) and the fastest velocity (produced by Remington), with the latter having an average velocity of 843 fps. Primers for.45 ACP Sport Pistols can significantly increase velocity.

Some primers may also enhance the sport pistol’s accuracy. The results showed that the smallest group size was achieved with a Remington primer (1.2 inches) and the largest group size was achieved with a Federal Match primer (3.0 inches). Readers should not take these comparisons as gospel and should experiment with different brands and types of primer to see which ones their loads prefer.
During my practice sessions, I did notice one positive thing. The smoke output from a sport pistol is minimal. Based on the low smoke output, this powder appears to be cleaner than the others I’ve tried.
The sport pistol has some great options. When used with a properly matched bullet, it consistently meters, burns cleanly with minimal smoke, fills the case well, is temperature stable, and achieves impressive precision. The fast to moderate burning speed of this powder means it won’t produce the highest velocities, but it is cost-effective and produces accurate shots. It can be obtained.

Tried different powders for 9mm that worked fine but all had issues with metering. This one solved that problem, fine grain meters great and provides accurate loads.

This powder meters very well out of my Hornady LNL Progressive press powder hopper. It has good case volume and seems to have good and consistent ignition. The powder is similar to Power Pistol in my eyes, without the extra flash. Even with a near full charge with plated bullets in my 9mm, the cases only fly about 5 feet or so from me, making brass policing easier. I will definitely order this again…I just wish it were easier to find.

Have loaded 300 9 mm rounds an they all shot accurately. Gun was still pretty clean. Plan on getting more of this powder

My favorite powder thus far. Cool and clean burning, meters very well, and has load data for polycoated bullets! The only bad thing about it is that it’s not easy to find.
