View Full Version : Dri-Moly in the Bore - Any Downside?

June 2, 2000, 08:44 PM
After cleaning my handgun barrels, I run a wet patch of Birchwood Casey Dri-Moly down the bore several times. It does a great job of preventing copper fouling from sticking to the bore and makes subsequent cleanings much easier. Is there any downside to doing this?

Faiello5, I can't think of one. George

For handguns, no reported downside. There are reports from M1A/M14 shooters that moly in the chamber on those guns seems to increase bolt velocity. I would not shoot moly in my M1A.. Or my 10mm Delta Elite.
