Or for that matter, for Smokeless Revolver Cartridges, which are still low end of the scale for pressure?
.44 Special, .38 Special, 45 Colt, .38 Long Colt, .38 S&W, .44-40, .455 Webley, .44 Russian, .32-20, etc?
I have been using just plain Bees Wax for all Black Powder Cap & Ball Revolver ( thin Bees Wax impregnated Paper Towel 'disc' between Powder and Ball or Bullet or Boolit ) and all my Black Powder ( ditto ) and Smokeless Metallic Hand Gun Cartridges ( I just adhere the same little 'disc' to the warmed flat Bullet / Boolit Base ) and the results seem to be perfection...even if it fell of in the Air Gap in a Smokeless Cartridge it would work the same and not bother anything anyway...none of these are ever max loads, and none are ever with Bullseye.
Is anything really better?
And if so, how so?
And is there any reason plain Bees Wax would not do just as well in higher pressure Hand Gun Cartridge like .38 ACP, 9mm Luger, 9mm Largo, .38 Super? .380, .45 ACP? ( with Lead Boolits, no Jacketed or FMJ in my own use, ever... )
