People used to shoot "corrosive" ammo for ages and during WW1 and WW2, but we still can find a good rifles with nice bores. Just clean it after each shoot with warm soapy water, clean it and use regular cleaning procedure and you'll be fine.
Note, that lacquered ammo isn't the best for bolt as it was designed for semi and full-auto. Try to find brass cases or bi-metal ones (plated).
