Using LNL bushings and lube dents

Okay, I have loaded a ton of .223 through my RCBS small base dies with my rockchucker press with no problems. About 6 months ago I bought a LNL AP and was really enjoying making a few thousand rounds of 9 and a bunch of 38 and 357. If you have been following the tumbler media threads you will see that I just bought 40lbs of corn cob media. Well, I polished up about 5000 casings for .223 and started loading them up. I used to be able to see the extra lube get pushed out the vent hole in the rcbs die, but now that vent hole is covered up by the bushing. EVERY SINGLE casing is now getting lube dents. Any ideas on how to fix this issue besides buying a dillon carbide die?

I have not changed lubes or anything. The only difference between the thousands of rounds I loaded on my rockchucker and the few hundred I loaded on the lnl ap is the press and bushings. Any ideas would be appreciated.

Cut a small slot on the inside of the ring where the hole is. Change rings if you can't with the one you have.
 
Or, drill a small vent hole where the die is exposed. I did this with a Hornady .223 die whose tolerances were so tight that when I added the Microjust stem it created a seal so tight that air couldn't escape. I used a small cobalt drill bit to drill a hole into that cavity to vent the air.
 
Plain & simple.
You are using too much lube.

I have never had sizing lube squirt out of the vent hole, ever, in 50 years.

All you need is a very thin film of lube on the case.
Wipe them clean with your fingers and what is left is enough to do the job perfectly.

Nope, sorry but I know how much lube it takes. I did not have this problem on the rockchucker press. Trust me, if you do 1000-2000 pieces of brass in one sitting the lube builds up. It has to go somewhere. I tried using less lube and all I got was about 4 stuck casings. It is definately a fault in the bushings. I even took the dies and polished them and it only helped a little.

Anyone who has cut or drilled into their bushings please post pictures so I can get an idea of how to start.

I use an L'n'L with the std bushings and have never "gushed out lube" from any brand of die.

It is a matter of too much lube - you also might want to break down and clean the die now and then.

Okay then what kind of lube are you using?

Could temperature make a difference? Like I said, I have done thousands of rounds without getting these dents from my rockchucker press. If I don't use enough lube I get stuck cases. What more can I do?
 
I use Imperial or wire pull lube - either seems equally good. A little on the fingers for each case and every third one I wipe the case mouth across my thumb. Haven't stuck one yet (knocking wood).

I can assure you that's not a workable solution to your excess case lube problem. The Dilllion carbide rifle dies need lube too.
 
The only time I get case dents is when I use too much lube. I use RCBS Case Lube 2. Try reducing the amount of lube just a little bit. I load on a LnL also.
 
I have loaded thousands of rifle cartridges on both the RCBS Rock Chucker and Hornady L-n-L AP without encountering lube dents using the old RCBS lube and Pad, Hornady One-Shot and now home made lube with lanolin and isopropyl alcohol. The problem has to be with the amount of lube being used, I have even installed the L-n-L conversion on my Rock Chucker. Like rc and bryon said I haven't ever noticed lube coming out of the vent hole before. I don't have any experience with Imperial sizing lube but other here have sworn by it so try less but first clean your dies
