Nomadicone:
When I first started loading my .357 magnum and my .44magnum I used Lyman's 158 gr. and Lyman's 240 bullets. Both are gas check bullets. At first I used gas checks because I thought that they were necessary. One day I ran out of gas checks so I lubricated the bulletw without gas checks: Allox lub fills the gas check grove. After I shot them I expected to find my barrels leaded. To my suprise it was clean. That was twenty years ago and I havn't used a gas check since and I've had no problems with lub contaminating my powder.
