How large do you let them erode prior to replacement? Thanks.
Recent counting indicates 300 shots, or more, is reasonable. The limiting factor is when the flash hole gets large enough to allow powder to sift through, or when the primer starts leaking soot between the cup, and anvil, indicating excess pressure. About 0.037" seems to be the very upper limit, but others may have differing opinion.
