I load both .44 mag. and 30-06.
I won't say case life is indefinite but most of mine have lasted through dozens or reloadings. This with charges from mild to wild.
I do inspect frequently. If several in a lot show signs of fatigue I will anneal. That is not often needed.
Military 30-06 brass lasts much longer than commercial because it is thicker.
Use and enjoy. Do inspect at every state of reloading.
I consider the case cleaner (I use a tumbler) to be one of the most important tools in a reloading shop as it allows proper inspection of the brass. That is a major safety consideration.
