Home Forums Hunting & Shooting Ask The Gunwriters 223 Rem, New school or old school twist rate?

I have a .223 with a 1:9 that shoots 55's to 70 grain bullets well, but my main long range rifle is a 1: 8, and , and I plan on rebarreling another action to 1:7.5.
These are long range TR rifles though , not hunters .
