I've tried searching for this and couldn't find anything, so sorry if it has been covered already.
I'm new to casting and have been PCing for 9mm and 300BO using shake and bake with good results. I'm looking to start casting for some of my other rifles (223, 6.5 creedmoor) and I'd like to PC. I realize coatings are just one of many variables in developing an accurate load, but it seems like there's not much data out there on PC in rifles so I'd be curious what type of accuracy people have gotten and what coating methods they use.
My question is, does ES coating offer more even coverage and thus better accuracy potential or are they just pretty?
