what does the "Euwin" designation represent? i got some and the bearing surface seems to be longer than some of the heavier 6mm br bullets. couldn't find anything on berger's web site. plan on trying LT 32 powder and expect small holes, as my 14 twist 6 br is doing this with berger's 64 columns and 65s as well as lahr's 66s. i like to varmint hunt and i hollowpoint these target bullets and the "Euwins" have a very large empty space in front of the lead core and should REALLY come apart. what's special about these? thanks.
