having fired nearly a quarter of a million rounds of cast bullets in everything from 380, 9mm, 40, 357/38 7mm tcu, .308 rifle, 41, 44 mag, 45 auto and 4570...
I don't know what is experienced but i think i would seem to fit the definition..
most of my experience has been with higher pressure calibers...with the exception to the 45 auto.
I am not sure that the smoke actually comes from the lube (at least all of it anyway...)
I have tested different powders, bullets and lubricants to come to the following conclusions:
flat base bullets smoke less than bevel based bullets.
Lee Liquid Alox smokes less than hard commercial lubricant.
the above mentioned alox applied to commercial cast bullets REDUCES the smoke...
Gas Checks almost eliminate smoke. very little smoke from my 44 mag TC contender shooting 330 Grain hand cast gas checked bullets. That was a max load with Win 296 powder for 1350 fps.
9mm seems to be the most peculiar about cast bullets (short light bullets, fast twist, fast powder and 35Kpsi make problems)
some powders smoke less than others...even with jacketed bullets.
commercial bullets are cast sometimes too hard for some loads to "bump" them up to fill the rifling and seal the bore, thus getting gas cutting, throat leading and increased smoke.
and here i stand waiting on the ATF to get me my paperwork for an 06 FFL for a bullet business..cast bullets to be exact.
I know shooters believe the hard wax lube is to blame for the smoke, I don't believe that. It is my belief that the smoke originates from exposed lead bases being burned by the high flame temperature fast burning powders coupled with the bevel based bullets funneling the hot gases in between the bullet and the bore specifically in the throat causing gas cutting and ultimately exposing the hard lube to the propellant gasses thus contributing to the smoke.
Countless hours of experimenting and testing leaves me here: a coated bullet strikingly similar to several others on the market but in my testing. show less signs of leading and smoke in my guns.
