I just anealed 350 38/55 cases that I bought when my CPA Rifle was built in 1993. Well over 10,000 shots fired out of that lot of 500. Some needed it some did not. Brass will tell you when it needs to be anealed by the way it sizes . Other 150 I formed into 32/40 and fire much less. They don't need it yet.
Higher pressure cartridges need annealing more often.
