Winchester Smokeless Powders have been around since the late 1800s. Customers that have shot Winchester factory-loaded ammunition know the 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 the preferred powder for competitive pistol shooters. Delivering superb performance in the 38 Super, 9mm Luger, 40 S&W, and 45 ACP, Winchester Autocomp powder can be used in many other pistol cartridge recipes.
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.
Bullet, Primer, and Powder Combinations FAQ
Can I interchange a rifle primer with a pistol primer if I run out?
No. Always read the data for the cartridge that you are going to use and only use the components that are indicated. The components that are listed are tested extensively to ensure that the data is safe for use. For safety, follow the data exactly and you will have no problems.
How far out do I set the bullet in the case?
Your manual will give you the correct length.
I seated the bullet in too far, do I have to throw it away?
No, all you will need to do is to purchase a kinetic bullet pulling hammer and follow the directions listed by the manufacturer.
As I checked my finished rounds, I noticed that some of them had the primer protruding slightly. Can I set it in further by using my priming tool?
NO! You could cause the round to discharge. You can use a bullet puller to remove the bullet and powder and then reseat the primer. It should be said that this is something that should be checked immediately after the primer is seated.
I left powder in my measure and I am unsure of what it is. What should I do?
Do not take any chances – discard it and use fresh powder which you know is correct.
Can I use “pulled” or old surplus military bullets?
Yes, you can. The bullet must have the correct diameter and the correct weight for the cartridge and the powder that you are going to use.
I dropped my bullet on the tip and now it is deformed, can I still use it?
Yes. Although, a deformed bullet may impact accuracy.
