Unknown primers

[bigbuckjeff]

I have about 3000 small primer that are unknown to be small rifle,small pistol,small pistol mag or small mag rifle. Would it be safe to load 357 mag for a revolver using them?
thanks

I ALWAYS apply caution with reloading components. Disposing of unlabled primers or powder is cheaper than a trip to the hospital. There are some things that won't grow back. Besides, would you have acceptable reloads?
