Hi! I just had a custom mold made for my 577-450 double rifle, it is .465 diameter. As there is not a sizer die made in this diameter I am planning on pan lubing. I have heard of different ways of melting the lube, over steam, in an oven, and on a electric stove burner. I know you don't want to get the lube to hot and burn it. So my question is what is the best way? Also I will be using SPG or an SPG type of black powder lube. Thanks for any help. Al
