But don't be surprized if they don't shoot exactly the same. Carbon arrows tend to degrade spine with use, and at different rates from arrow to arrow, so they probably won't group as tight as your new ones. As long as the brass inserts don't mess up their spine - I'm feeling too lazy to check the charts this morning, so I'm leaving that one with you - they'll do fine for close range hog poppin' or small game busters.
