I couldn’t agree more. I use their recommendation as a guideline only.
On another note, that bullet was designed for 22-250/220 swift velocities, I’ve read multiple reports online that this bullet out of a 223 does not perform well on coyotes or bobcats, but does well on deer.
In the end, until I try it myself, it’s just stuff that I read online. Hopefully this fall, I will get to find out.
