Fairly certain 25 it is. 9 twist for the 120s. I have several .243 rifles so going for the heavier bullets. Not interested in building the lightest rifle possible so thinking KS #2 contour at 22". Seems like a 20" featherweight #1 would be too short?

Thanks for all the input so far. Considered a 280 AI but have 270 and 06 rifles already.

Please feel free to set me straight if I am confused. Basically looking to build a light medium long range gun without too much recoil.
