Water filled ziplock bag at 50 yards. Polymag was captured in a towel behind the bag. Impressive expansion for 50 yards. I haven’t shot these in years and I was impressed with the accuracy at 50 yard from FX Impact with STX liner.
Anyone have Polymag pellet expansion pictures after hits on pests? I have recently killed pigeons out to 60 yards but pass through on all of them, no pellets recovered.
Water bags are not a good substitute for animal tissue. That's why they came up with ballistic gelatin which is closer but far from perfect. Next time you shoot a animal save the carcass and use it for expansion testing.
