I was surprised to hear that advice from a gun store
I have full length resized my .243 pig loads for over 30 years, and I have cases from my first ever loads done in the 1980's (PMC). Some of them would have been reloaded many times. I do not record such info, just watch for signs of them getting tired. Neck sizing will give better accuracy, and you would think the brass would last longer. But for rounds that I want loaded fast, and as slick as possible, like when you are firing multiple shots quickly, I go full length. So I think it depends on your application, not just accuracy and case life.
