I've never used the A-max on critters. But, I have found that the Hornady 52 gr. A-max is the best grouping bullet for my old Ruger 220 swift /ubbthreads/images/graemlins/ooo.gif. I am very fond of that bullet.
I know they are very different than the V-max in that they are not made for dramatic terminal ballistic performance.
A-max's are really made for match shooting. They look the same but there's a big difference in the way that red tip is designed for the two different bullets. The A-max tip is not made to promote expansion (or even mushrooming) on impact like the V-max. The A-max jacket is also thicker... the tip is there for aerodynamics....increasing the ballistic coefficient.
The V-max tip actually helps the bullet open up when it hits it's target. It's like a little wedge that mashes into the point end of the jacket and starts it's expansion. Here's a link to the Horndady website:
https://www.hornady.com/shop/ If you click on "more info" for the bullet you want to read about it will show a nice cross section illustration of the bullet with an explanation of it's design.
For me it's very tempting to use my best grouping bullet for hunting. But it's not smart. This particular match bullet would probably go straight through a coyote without expanding....unless you hit solid bone. That's not the way to get one-shot kills. Besides, when we hunt coyotes we probably don't need to think "Minute of Angle" but we should think "Minute of Animal" /ubbthreads/images/graemlins/smiliesmack.gif.
Check the Hornady website and listen to them, not me. /ubbthreads/images/graemlins/grinning-smiley-003.gif
