Brent,
Your right the .32 Miller Short is a straight walled case. The case is based on a shortened .357 Max. case.
Just taking a guess I'd say that those shooting lubeless bullets are shooting them out of a custom or very smooth barrel. Then you could have a well “seasoned” barrel, either from pre lubing or firing quite a few shots in the normal way to get enuf lube on the bore surface permiting shooting “X” number of bullets with no problems.
I'm reminded of shooting .22 RF's. Some conventioal thinking is that you don't clean the barrel for at least 500 shots have been put thru it, or until a noticeable drop-off in accuracy is noted. After cleaning it takes about 50 shots to bring it up to normal accuracy. A similar thing happens with big bores shooting bullets with to much lube on them. After a few shot you'll get a “wild” shot and then the gun goes to shooting as expected. I call that off shot “lube purging” and is cured by not filling all the grease grooves with lube.
So, it wouldn't really surprise me that with the proper amount of lube “seasoned” into the pores of the barrel you could get any amount of shots fired with no lube on the bullets and no Leading.
Of course this is all just supposition on my part as I've never tried it outside of shooting paper patched bullets.
