A 7 twist standard is not going to happen.
The high bc 257 bullets aren't in weights that have any advantage over 6.5s.
Yes, but if they started to make 100-120 grain high bc bullets (which is what I'm advocating) then there would be an advantage over both 6mm and 6.5mm, via that weight category. You need a 7 twist for the high bc mono bullets in that weight category.
