Tumble lubing traditional-shape bullets
I know there are specially shaped bullets these days that are specifically designed to be tumble lubed (such as having narrower and shallower lube grooves than bullets designed for traditional lube) but what I want to know is if it's possible to tumble lube traditional shaped bullets too instead of hand-lubing or pan-lubing. Because I'd much rather do that than those two methods. I have some liquid alox sitting around that I feel would work really well for this, but if anyone has any experience tumble-lubing traditional bullets, I'd like to know how well it works.
One thing that might be relevant is that the bullets I'm considering tumbling are part of an experimental batch; 100 9mm bullets made out of pure, unmixed linotype. So these are REALLY hard bullets that I don't expect to expand in the bore AT ALL. I'm not entirely sure if that'd make a difference in whether tumble lubing would work here, but any insight would be nice.

traditional bullets - tumble lube - Linotype- diameters.
Tumbling- I used Xlox on traditional 45 acp lswc as cast .452" diameter bullets for a test. Works ok. Watch for lube build up that may change COL. in the seating die. I prefer to use my Lyman 450 to size and lube over tumbling.
I have cast 45 acp & 44 mag, using Rotometals linotype for a test. Can a alloy be to hard? No.
The bullet diameter has to fit the groove diameter. Same or up to .001" larger. The standard sized bullets of .452" & .430" worked well in my Gold Cup & M29.
I have not tried Xlox and linotype together.
