These are .375 winchester. Gulp, using new winchester brass, with a lyman 248grain bullet. They were not powder coated but sprayed with vht engine block paint. I am experimenting so this is just me trying to figure it out. Paint adds about 2thousandth in diameter to the bullet. I sized these bullets naked to .376, would have rather had a .375 die, then painted and cooked. I then resized them to .376, and didn't have any issues with the paint coming off. Went right through the die easy.
I have been messing with some .44 310grain bullets, I did not size them before powder coating, and the sizer die to bring them from .434 or so back to .431 was rubbing some of the paint off.
I should have sized them from the mould to .429, applied paint, cooked, and sized again to .431 which is what i wanted.
I still don't have it down right on the right quanity of powder to tumble with, and i am either getting too much paint, or blotchy . [Linked Image]
