Might want to try this

[Roadkill]

I've been loading and shooting 9mm using 5.7g Unique with a 125g Lrn bullet in several 9mms, done several thousand now and they do very well. I was having real problems with .38s though. The recommeded top end load was 5.7 g Unique with a 124 g bullet, I could not get consistent powder ignition. Last 500 resulted in about 1 in five not igniting. CCI and Winchester primers both repeatedly failed. I think the problem was too much case length for the volume of powder. When I loaded the last bunch I used 5.7g again but cut a small cube of styrofoam and packed it on top of the powder, this filled up most of the empty case volume, leaving room for bullet on top. Nice and snug. Fired 100 rounds, excellent results. The styrofoam kept the powder to the rear of the case for ignition, was no appreciable increase in pressure, and disentegrated when ignited. For you who use powder with less volume might want to try it.
