I received some 158gr SWCs that are .3615 .362 would running them in the tumbler with media reduce the size, the coating seems to be to thick
Short answer is NO, it will not reduce the diameter. If you castresize to .359 or smaller, this will not damage the coating. If not send them back.
WHAT BRAND ARE THE BULLETS?? Just so we know who not to buy from!
all you need is a Lee bullet sizer die and a quick spritz of hornady one shot to make everything right
It works just fine! I made some .355 from .358 that were coated and all that happened to the coating was it polished up a bit. I ran them thru with no lube and had zero problems!
