I have reloading capability if I want to...should I??? what bullet? what recipe? Thanks.
What you need to worry about is your barrel's twist rate matching the bullet's weight. Not the length of the barrel. Sure, 20" vs. 24" barrels, we all know which one will have faster FPS but that hog, deer, or a yote won't know a darn difference if it's dead. Great thing about .243 is that there is PLENTY of factory ammo to choose from. 20" barreled rifles are my favorite for hunting applications.
