I should add, that although the Berger's are a bit pricey, I think they are very much worth it.
I use mine on gophers PD's and coyotes and fox, and the Bergers perform beautifully in every category.
If you are going after "goo and pop" type performance on rodents, the 20gr V-Max shines, and the Z-Max is the same bullet only more cheaper.
Hope this helps.
