Lubing brass that has primers?

[Tango Sierra]

I'm going to start reloading 357sig and I bought some Winchester brass that already has primers. Will Hornady Brass Lube cause problems with the primers?

Hornady 1-shot would work fine. However, brass is normally resized before being primed. Are you sure that you need to resize the cases? Sizing is the only step where case lube makes any difference (keeps brass from getting stuck in the sizing die on non-carbide die sets).

Well, if the brass has primers, it woudl stand to reason the the brass has already been resized.

Why are you wanting to put lube on the brass?

So, the recommendation is to pull my sizing die from the press when reloading this brass? I'm new to this reloading business.

Your 357 Sig cases will be the proper size, but there's the possibility that the case mouths may have been battered in transit, and with this round you'll find it necessary to slightly bell the case mouth anyway. I also chamfer the insides of the case mouth for this round, since it needs tight tension to hold the bullet in the short neck, and I don't bell it much at all.

Take the sizing die out of your press and load as normal. The over all length on this cartridge is critical, as well as the neck tension I mentioned. This is a high pressure round, higher than .40 S&W, so you don't want bullet setback with it, which would increase pressure. I've found that powders that are slightly compressed help to prevent bullet setback. My favorite powder for 357 Sig is Accurate #9, which gives exceedingly excellent accuracy in both of my handguns chambered for it.

Hope this helps.
