i agree with that barrel twist is also a big factor when deciding on a barrel. bullet weight will be a factor when deciding barrel twist. now as that i have both of these calibers, a remington M700 26" barreled 204 and a bushmaster carbine 5.56mm w/ a 16" barrel. so these are two different types of rifles, both in the calibers you are interested in.
