I tried the 55gr Btip, at 3,950-4,000fps, in my 243w and had floppers and runners, even had one get away from me, leaking out both sides. I am not impressed at all on coyotes.
I've not used the 58gr Vmax, but have used the 75gr Vmax, and that is an impressive bullet. I went 33-34 coyotes straight without an exit, ranges from 20 to just over 400yds.
I get the opposite results in my son's 223wssm between the Vmax and Btips. The 60gr Vmax at 3,700fps results in frequent splash wounds, but hammers them down, whereas the 60gr Btip at 3,700fps gave us runners and floppers.
The 55gr Btip in my 222remmag at 3,450fps is great, with very few exits.
