Quoted from slochar:I think it's the plastic the targets are made out of. In my tests, there were 2 types of vintage targets, the 2 that have the translucent plastic drop without bricking 99% of the time. The center drop isn't translucent (even though it's the correct hot stamped design) and drops without bricking about 95% of the time. I don't know what the difference in the plastics is though. I have a couple boxes of about 100 drop targets I've collected over the years that I pull from for replacements.
I should buy a couple of the new ones on my next PBR order and see how they work out.
I find the ones from PBR brick just fine if they take a hard direct shot. I strongly suspect the plastic used today is just to far flexible and the head of the target whips back and forth so fast the catch doesn't release.
