Most of these bullets tested through the carpet, plywood, and water jugs, i have never hunted with. Reason is i have mostly hunted with Deep Curl bullets. Most of the Deep Curl bullets i had, i sold, because it seemed they were too valuable to shoot at anything but animals.
However, this particular bullet i have hunted with, and do have some first hand knowledge of how it performs on animals. What i did seasons ago, was spot a herd of antelope in the evening , and sneak on them the next morning. My sneak went well for hundreds of yards, but finally the terrain exposed me, and it was about all i could do to crawl on my belly and get as close as i dared. It was very difficult to range them, because of the grass, and the range finder kept reading 30 yard. Finally it read 340 yard on the hill behind them, so i figured i had a 325 yard shot. I was in full view of the antelope herd, so i decided to shoot while i had a chance. My tag was good only for antlerless, so i carefully glassed the herd, and found a doe that was sleeping kinda broad side to me. After breathing, and practicing, i took the shot. The bullet hit high through one lung, and clipped the backbone. She, never got up; she died in her bed.
The rifle used that day was the same rifle used this day. However the powder charge that day was 115g Blackhorn.
The gps fell out of my pocket whilst crawling like a snake, but it was easy to back trail, because of the furrow i left in the grass.
That picture of my crawl trail, always makes me laugh. Another good happen, was i never crawled into a cactus. After being able to stand, i ranged the dead antelope at 314 yard from where i shot. Two deer also fell to this bullet. One was at about 110 yard, and the other was out at 173 yard per the range finder.
There was no evidence on these 3 animals that the bullet failed to expand.
So far I seem to read about more reliable expansion with the 200 grain over the heavier 250 and 300 (Non- bonded). I am still on the fence about the bullet and still wonder what the reasons are. Pellet loads seem to be one reason, both me and my Nephew were shooting pellets loads at the time, so I am thinking that Velocity is a big reason for the issues some have had.
