Interesting study but I dont have the time to review all the data, even if it was in English.
I would like to see the data broken down by the total numbers of animals shot with each caliber plus the mean and median and distance traveled. Bullet type and weight would be nice to know also. IMO the total numbers of animals shot with each caliber is key. If only 2 were take with a 458 while 200 fell to a 308 then the 458 could be skewd by a lot of factors while the 308 numbers could be considered more representative.
