ive tried all sorts of bullet weights/types in my (308 browning xbolt 20" barrel) but never been quite happy with it, thats until i went to see mike at brock and norris rifles for some reloading consumables.
and i asked him for some advise on a good 308 deer load and his response was a very quick one, this is what i use in my 308 give it a go he says
180 grain sierra sbt (code2160)
44.3 grains of LOVEX S065 powder
federal large rifle magnum primer
im using a hornady match case but mike would proberly use laupa ??
Anyway it shoots great not too fast at 2302 fps but speed not everything is it.
i will be sticking with this load to shoot everything from muntjac to reds
below is two shots at 150 yards
