Not sure on pulling heads they may pop first I would think not sure. As for yield fluctuations with same material is due to packing and grinding I believe.So after plenty of runs and slabs I changed my oil and noticed particulates in it and was wondering if there was a way I pulled out heads while pulling a vacuum on my tube so I can pressurized before I add butane to soak. I got on average 10% yield from my larf runs but some where as low as 5% when it was the exact same material blasted done the exact same way and everything
