I agree with the numbers above but the 230 is reported to be a little thicker in the jacket (approx. 003). The performance im seeing backs that up as I wasn't getting pass throughs on even small Texas deer with the 215.
I'm a believer that velocity isn't the end all be all with bergers considering the bc and weight. I'm thinking of building a short barreled 300 short mag with a goal of 2600 from the muzzle. That will get me 2000 fps at 500 yards. Should be a great deer lease rifle where most shots are under 300 yards.
