The 40 gr V-Max has been my go-to bullet for my Axis .223 since I bought it 10 years ago.
when I bought the gun I knew a buddy that has an extensive collection of half used boxes of .223 slug so I tapped him for a bunch of different weights & makers to dun a comparison test.
My gun shot anything under 55 gr very well, heavier than that, the groups started to open up a bit, still within an inch or so. 55 gr or less were all within 1/2 inch, but those V-max's shot one hole groups one after the other. and they hold that accuracy out to 300 yrds very well, I have a life sized A-500 gopher target that I can set up on my property and have yet to miss that little guy at 300 ....so far....
I have shot yotes from 50 yrds to 300 yrds with them and haven't had any of the failures some folks write about...not one of them had blown up on impact. I have never shot a deer with one ( illegal here in Ab.) but wouldn't hesitate if I could.
