Winchester AutoComp Smokeless Gun Powder
Winchester Smokeless Powders have been around since the late 1800s. Customers that have shot Winchester factory loaded ammunition know that quality of propellant they’re receiving as soon as the first shot is fired. Bring that quality home to the reloading bench with the Winchester family of powders.
Winchester AUTOCOMP is a ball powder designed for competition race guns. A perfect burn speed to feed the compensators with a higher volume of gas, it is a great choice for 38 Super, 9mm, 45 ACP and 40 S&W. With AUTOCOMP, competitors get off faster shots with minimal muzzle flash.
Other Important Information:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.

AutoComp is the best powder i have found to load out of my Dillion in that it is very consistent with the powder charge in my 10mm

I like AutoComp a lot. I use it for 9mm, 40 S&W, and 45ACP. It burns clean and gives me consistent performance. It also meters more consistently, than any powder I’ve used, in my Dillon powder measure.

I like Winchester powders because they are easy to meter and consistent

I use this powder for .380 and .40 with Federal Primers. It is an excellent power. Measures perfect with the Lee auto disks. Powder is very clean burning. I used Unique when I first started reloading. I tried the AutoComp and never looked back. After firing 300 rds I barely have to clean the gun.
