I've fired that same Winchester load into a 50 gallon barrel of water from less than 10' away out of a Ruger 77/44. This load generates around 1,800 fps on average from that rifle, it barely expanded given how tough a water test is on a bullet, especially at that range, I wasn't at all impressed. IMO Winchester should at least notch the copper jacket to aid expansion and, I'm no metallurgist but I think their lead alloy may be a little too hard as well. I've taken deer and seen others take deer with this round and it left almost no blood trail to follow. It's basically a .429" hole punch, it'll get the job done but, you'd better have some patience and passable tracking skills.
After testing and field experience with the WWB rounds I tried the Ferderal AE jhp round mentioned above and have found them to be loaded essentially to the same velocity as the WWB's (I did not have to change the zero on my scope
), they group excellent as well. Terminal performance was day and night better also, blood trails that Hellen Keller could follow. I'd love to see how the Federals stack up to the WWB in gel tests.
Always enjoy watching your tests, thanks for your contributions!
