have always hated the 270, 7mm and 3006 mostly due to guys I knew that shot them thought anything else was for sissies or idiots. also because I grew up shooting a 243 (and still do sometimes) and was always made fun of (until they saw the truck loads of AL deer I killed with it and outshot them at the range).
Have warmed up to the 3006 over the years but I have always been an off caliber type guy. Always loved the 6mm, 260, 7mm-08 type guns personally. I just always liked to be different I guess.
