I have cast and reloaded before, but up to this point I have been using powdercoat. I want to use a traditional lube for the RCBS 35-200 that I cast for my 358 win. Reason being the gun chamber was cut by MBT, and I am trying to replicate the load he has found best for the 358 win. Lube is white label 2500. Like the title says, what are things I need to watch out for? I plan on pan lubing as budget does not allow for a lube sizer right now. How long will the lube still be good? Will i need to shoot them within a certain time frame? Will my lube work from temps 20-75 degrees? What about powder contamination? Those are some questions right off the top of my head.
