If all you are using is BLL no regular lube I actually dry them in my toaster oven for 20 min at 175 between coats and it sets the coating like a varnish and shoots clean with zero residue. You want to go light on the coating it’s like brill cream a dab will do ya…
I use this lube and method on all my gas checked rifle loads with superb accuracy and mirror bright bore with no leading.
I use two coats with a “cure” in the oven on each coating.
Nothing comes off on my loading dies and they are slick and sticky free during handling.
The calibers I shoot this way are 7.62x39, 45-70, 44 mag, 357 mag, 30-30, 308.
Not shooting super velocity loads but good enough accuracy to cleanly harvest game to 200 yards with the appropriate cartridge.
I size all of the bullets 1 thou over bore diameter any more than that and I start to get leading. My theory on that is it’s not compressing the bullet to fit at that point it’s scraping it down to size and I am loosing my lube layer. Not 100% sure on that but if it works don’t fix it
My 7.62 ruger will boringly ring a 6” steel plate all day at 300 yrds with my 13 year old son shooting it.
Hope this helps you out!
