Since I am no engineer, here is a link for twist rate. http://www.realguns.com/calculators/riflingtwist.html

A 130 .257 is going to have to be 1.5 or so inches and I am doubting you can get much more than 2850. That puts the twist requirement at 1 in 7.9. Which is really close to my 260 with a 1 in 8 twist running 140s.

Play with a 100 or 110 with that calculator and you start seeing the twist rates that are offered by manufacturers.
