My go to bullet is the Barnes TSX or TTSX. They have never failed me, but on smaller game (whitetail does for example) the animal will take a death sprint, sometimes a good 50-100 yards. However, they always leave a blood trail that even an old, fat boy with glasses can easily follow.
I have experience-based confidence that a Barnes bullet will reach the vitals, regardless of animal presentation. I know there are exceptions out there, but I have not seen them. Other than Barnes, I like Norma and Nosler. However, Nosler has priced themselves beyond their value. Looking on Midway recently, they cost more than Barnes and are just a few dollars cheaper than Swift. I am loading up some heavy for caliber cup/core bullets (220gr Rem and Hdy for example) to use on my favorite test medium, the Texas feral pig. I also plan to use them on whitetail this year on our lease. Why? Because I can choose my shots on our lease there and sometimes it's good to do things the old-fashioned way.
I went to the Fox bullets website and the bullet is interesting. I don't experiment with loads like I did years ago for various reasons, but I would like to try their bullets. For it to be on my starting lineup, it would have to be cheaper than Barnes, more available than Barnes, or more effective than Barnes. If they expand better and at lower speeds, it could be more effective in stopping the "dead doe last act of defiance sprint". I call it that because they always make it through the mesquite and drop in a nice, thick, cactus patch.
I have used copper bullets from Barnes, HDY and Nosler in .243, 7x57 and 30-06 on deer and pigs for comparison. They all seem to work the same.
@RAVEN ROCKS PRECISION, I appreciate what you are doing here on AH.
Safe shooting
