I've been shooting Berger for many years. On blowing up, I shot a 3,000 water buffaloe at 70 yards last spring in Argentina and it went through its shoulder and out his lungs and I could put my fist in the hole where it came out!! I'm not going to believe anything on that. I was shooting a 195 grain bullet in a 300 Norma mag .284. In the same rile, I shot 180 grain Berger Bullets until the 195 grain Bullets came out and on my 1,508 yard target the 180 explode and hit like a bunch of bb's at that target about half of the time. This gun, and I have two of them pushes the 180 to fast with to much energy for a 180 grain bullet. I have a 1,038 yard target and they hold together well out to there.
Hope this helps w,
Harvey
