I can't see what all the hoo-haa is about...there is about 10 gr of H2O difference between the cases...that's about 2.5% difference in velocity or 70-100 fs if both cases are loaded to the same pressure using the same bullet weight. Not enought to waste all this time or space over whizzing in the wind.
I can't see hardly any difference in the case other than the x62 is longer.
Interesting...I own a 9.3x57, and had a 9.3x62 for a couple of years. Both are 24" barrels, and I shot them side by side over my chronograph. All I can say is that the x62 ran 300 to 400 fps faster than the x57, depending on the load.
I don't disagree that most of the differences aren't relevant, until you get up to larger or dangerous animals. Then I think a 286 gr bullet at 2400-2500 fps would make a difference vs one at 2000 fps.
AS far as the "hoo-haa" concept -- well of course we do...
. That's half of what participating in a forum is all about...
