I have a couple I rotate through. Lately it's been the 22-250. Then I have my 6mm dti, if I get the AR bug. And I have my 6 creed which wears and eh1 instead of the krg bravo.
Thats dependent on the bullet. I tend to avoid vmax's for that reason. They have a thin jacket, and they will tear a coyote up if you hit bone with them. And they are even worse the faster you run them.
