It actually was something I saw on the internet when I first got into gun a few years ago. I always thought Remington made great stuff so I got some Golden Sabre's and did some testing myself kind of like how tnoutdoors9 does on youtube. I shot gallons of water and they worked great, also when I shot wet phone books they worked pretty good not very consistent though, but then when I put some denim and goose down in front of the target(wet phone books) they completely plugged and didn't expand. I think IIRC I fired 5-6 rounds and none expanded a few of them peeled back some but barely. I was pretty disappointed cause I was really liking the round until then.
I have also tested the same way Winchester Ranger,PDX-1, Speer GDHP,Federal Hydroshok and HST. They all tested pretty good the only real consistent one was the HST, they look like the star on the HST box every time. Speer was also real good in performance as well as the Winchester Ranger, the PDX-1 did OK but didn't expand completely every time and the Hydroshok did good as well but didn't expand as large as the others but they were the only non+P rounds of the bunch. I tested 9mm 124+P
