.45 Auto Win NT

 Currently, all domestically produced lead-free primers are only manufactured in a small size. So when ammunition manufacturers offer lead-free primered ammo, they make brass with small primer pockets regardless of caliber. In addition to Winchester, Federal also offes NT 45 ACP ammo; also equipped with small primer pockets. This brass may be successfully loaded. It merely requires you to sort it from the other brass and use small primers in it.

Will any brand of small pistol primers work or does this brass and the standard loads for .45 ACP require those "lead-free" primers?

 Any brand of small pistol primers is fine with this brass. As well, all piblished loads are fine as well.

I've heard about this new brass on another reloading website.  Yes, you use a small pistol primer but know nothing else about this new brass.

I have seen this problem with Federal .40 SW.  Most of the cases marked 'NT' will not properly seat a small pistol primer.  I have had sort out these cases from my other Federal cases and then deprime the cases and ream out the primer pocket.   Anyone else run it to this problem?

The .40 S&W NT brass you are running into may have been loaded for either the US Coast Guard or for the Dept. of Homeland Security. This brass has crimped primer pockets. After depriming, the Dillon SS-600 primer Pocket swager should be used to swage out the crimp so  the cases can be primed.

THanks Thats what I have ended up doing.  Slows the process down but once it is done then I can keep loading the cases until they fail.

At first I thought I was doing something wrong.
