.357 Sig Case lube

Yes, they must be lubed for sizing. The sizing die must be clean. If you get a dent in the case, it's because of something in the die.

Dillon case lube works fine.

I reloaded several hundred without any problems whne fired.

 

I sized mine in a single stage press before running them through my 650.

Dillon case lube will not concaminate powder or primers. To properly apply, lay the brass on its side, one layer deep, in a shallow cardboard box or cake pan. Spray a light coat, shake the container gently to roll the cases around, spray again. Wait at least 10 minutes for the alcohol carrier to evaporate, then load. We tumble the loaded rounds in plain corncob with a spoonfull of alcohol added for about 10-15 minutes to remove the lube.

Just loaded a small test batch of .357Sig and all I can say is WOW, the Dillon dies have far exceeded my expectations. Up until now, all I've loaded .357Sig with is a single stage press with Lee Dies which I HATE (I bought them almost 10 years ago because they were cheap and I didn't know any better). The effort requiredto run the cases through the resize die was unreal. With the RL550 & Dillon dies, using the exact same case lube (Sorry, don't have the Dillon lube yet, this was some Cabelas Lanolin-based lube that's suspended in alcohol), the effort required to resize the .357Sig was barely more than that required to resize 9mm, .40 or .38.

 

My expectations weren’t very high because I had tried a set of Hornady dies that supposedly had a carbide-like ring on the resizing die, but they were no better than the lee dies.

 

I don't know if it's the dies, the longer handle on the machine, or some combination of the two, but the Dillon .357Sig dies in the RL550 are AWESOME!

Dillon lube or Hornady One Shot are great, no need for the carbide dies nor do I find it easier to fist size with a 40 die followed by a 357sig die. Just use the Dillon steel die, mine most importantly sizes the neck perfectly along with the proper light to medium crimp I get no bullet set in any weight. Stay away from plated bullets in this caliber.
