Second picture of expansion

I only fired one round into some jugs for an expansion test (5.2" barrel), and saved the rest (had two boxes of 50). It expanded to 1.8x its original size, and retained 100% mass. And one shot accuracy test all ended up in a single hole. Overall cartridge weight varied by about 2-3 grains, although I didn't think to measure America ammo to compare; might do that when I get home. No velocity test though. Made it into the third bottle and slightly cracked the fourth (likely hydroshock). Bottle #2 was an Arizona gallon turned sideways (back to front longside, not top/bottom)
This is probably the perfect scenario for it though with a long barrel and only plastic.
I picked it up for my shtf hording stash and was highly sceptical, not knowing if it would even work properly. Now I'm more than happy to add it to my backup pile.

You mean a squib? First, I've been shooting long enough to know what a squib looks and feels like. Second, I reload so I pay attention to what ammo looks and feels like. Third this is shit hit the fan ammo. I've got ~400 rounds of Hornady/Sig/Remington JHP 9mm before I reach for this stuff.
Like I said. It's for stockpile, and will be squeezed after my good jhp, and before my fmj.
