I have shot 30-30,30-06 not a 308.
I have had ok luck with nosler 125 balistic tips.
I hear the Vmax by Hornady work well i think they are 110 grain.
As far as Vmax the only ones to date I have used are the 58 grain
in my 243 at 3800fps and they explode .
I plan on working up some for 270win ,30-30-,30-06 but have not done it.
