I went and bought these and the 50gr SEI today. Loaded some up and shot both - the 50 gr didn't perform well in my Colt HBAR 20" 1-7 more load work required. But the 63 gr over 24.6 gr Benchmark running about 2950 fps put the hurt on this yote today pictured below! Though the shot was a little far back- he took a step just as I shot! The hit spun him around -but he never went any where dropped right where he was shot!
Exit wound was about a 1" so I got a good mushroom!
