I haven't tried the Berger admittedly.. but if you have some, I am sure a local tree or two would give you the info you are looking for.. I typically look for what the exit looks like on a diameter of 10 inches or so of wood....
if I have a big exit, with wood blown into strips about 6 to 8 inches above and below the exit hole, then I consider that good to go..
yesterday I was testing some 90 grain ballistic tips, with an MV of 3400 fps, into a pine or two at 100 yds....all I can say is WOW!!! now I have to evaluate if the load might be too quick, and result into a lot of blood shot meat on a blacktail..
would definitely take down a good sized cow elk...or a black bear of good size... the exit looked like the back of the pine had been hit with a rocket launcher...
