At the risk of being pedantic, you say the twist rate needs to match the muzzle velocity to achieve the proper rotational velocity and then say barrel length doesn’t matter. 1:7 twist is common in 8-9” .300 barrels. Going to a five inch barrel and not changing the twist is going to reduce muzzle velocity and not spin a long bullet any faster.
