The work fine in a .308win. I've taken all of my fallow deer using them.
A wet newspaper test i did at 200y with a cows shoulder blade infront of the box showed that they penetrate around 12", and expand to ~50cal. some of them lost thier cores but still managed to penetrate to the same depth. retained weights were between 75gr and 120gr IIRC. The major wound channel for all of them was around 2" wide but didn't begin untill 3-4" of penetration (e.g the first 4" had a pencil hole, the last 8" was bigger than a golf ball).
Results on deer between 150y and 300y, all pretty much broadside shots. showed the same performance, leaving a golfball sized exit wounds and deer that didn't go more than 10-20m.
They get my seal of approval /ubbthreads/images/graemlins/wink.gif .
Edit:
They don't recomend Match bullets for hunting because some types like the Lapua Scenar act like FMJs. I've had small roos run off after being hit well by 155gr scenars.
