What do you think about tumble lubing jacketed bullets?

Been searching this forum for any threads on tumble lubing jacketed and plated bullets but came up zilch. Must be doing something wrong, but figured may be easier to just throw this question to all you guys.

Would a little LLA help squeeze a little more velocity and reduce barrel wear?

Thanks in advance

I've never found the need to lube either plated or jacketed bullets. If throwing something into the mix that wasn't really designed into it from the start, it may affect accuracy. The old law of unintended consequences........

Hope this helps.

Wouldn't stay on them anyway.

Plated & jacketed bullets have no grease grooves to hold lube like lead bullets.

The lube would be all scraped off the actual bearing surface of the bullet when you seated the bullet in a case.

It could also raise pressure.
Years ago, 30-06 target shooters liked to dip loaded ammo in grease to cut down on cupro-nickle jacket fouling.
The practice was traced back to several blown-up low-number 1903 Springfield rifles.

In the "For what it's worth" category, easyrider6042004@yahoo.ca, there are other coatings available for jacketed bullets, including molybdenum disulphide compounds. If you're interested, try "moly" or "moly coated" as a search term.

I concur with rcmodel. Adding lube to a jacketed bullet could dramatically increase pressures. Cast bullets are soft enough that the metal flows into the rifling and the bullet is easily swaged - pressures are low. Adding cast bullet lube to jacketed could cause lube to be forced back into the chamber and you could have a bad day. Read Hatcher's Notebook or Whelen's articles on this from the 1920s.
