This new propellant has no comparable market equivalent. It is faster in burn rate than Auto Pistol, and slower in burn rate than Clean Shot.
Every manufactured batch is tested for superior ignition with BOTH lead-free and standard lead styphnate primers. This ensures superior ignition to any other pistol powder on the market.
It is perhaps the most versatile of all propellants across the .380 Auto, 9mm Luger, .40 Smith and Wesson, .38 Special, 38 Super, and .45 Automatic cartridges. We have tested this propellant to a charge weight of only 3 grains in a .44 Remington Magnum with a cast bullet, and it STILL ignited well!
From a competition standpoint, Ultimate Pistols burn rate is similar to Winchester Autocomp. However, the burn rate modifier of Ultimate Pistol is incorporated within the propellant grain. This provides more reliable ignition and consistent velocity than competitor’s propellants of similar gas generation rate.
The grain geometry of Ultimate Pistol promotes highly consistent charging. With a volumetric powder dump, we have found total charge variation no more than “one tenth of a grain”. That’s +/- 0.05 grains.
The consistency of charging, deterrent location, burn rate and peculiar quality assurance testing of this propellant have proven to contribute to superior accuracy.
The gas generation rate of this propellant should enable 9mm Luger, .380 Automatic, .45 Auto, .38 Super, .38 Special, and .40 S&W loaders to reach “self defense” velocities, while maintaining reasonable pressure levels.
Too, this propellant works well at reduced charge weights for low-recoil applications. Shooters World tests and publishes real-world starting loads for all of our pistol propellants. We purposefully take our test load charge weights down to failure; sticking bullets in our barrels, squibs, short strokes, stove pipes and every other ballistic anomaly. Then, we clearly annotate with published reloading data where a hand loader can be assured of starting success.
Ultimate Pistol does contain a level of flash suppressant.
As with any propellant and load combination, a minor change to any of the components of the test load CAN result in significant shift in ballistic performance. This shift can cause unintended high pressures, and result in injury or death. Therefore, Shooters World LLC, nor the manufacturer of this propellant take no responsibility for the intentional or unintentional misuse of this product. The charge weights and results noted within are recommended, according to pressure barrels, actual firearms, and components used at the time of testing. It is the responsibility of the hand loader to utilize safe reloading practices, and always start with a safe starting load. The published data is shown merely as an indication of potential performance in one test load, shot by CIP, SAAMI, CUP, EPVAT or M83(strain gauge) standards.
