So like a rookie I purchased a Rem 700 in .243 because I thought that is what I want to shoot. I have since bought all the reloading stuff needed to load my ammo. I have bought bullets,brass,dies, etc. I have not bought a barrel to put on it yet and my gunsmith said he had a match XX douglas blank he would sell me for cheap. The barrel is 308. Should I stick with 243 or sell all my stuff and switch to 308??? I Will be mostly using this gun for matches 100-800 yards with the occasional 1000k shoot. Thanks for help.
