I was reading a thread on another site where the OP said he had loaded up a bunch of rounds of a specific load a couple years ago. It was a superbly accurate load at the time. Recently he tried shooting some of these loads and accuracy was poor. He put some of them in the press to try to seat the bullets a little deeper and he heard a distinct "pop" with each of them. He said they cold welded. My question is is this common and if so how do you prevent it? Is the answer to only load as much as you need at one time?
