Not at all, I've reloaded some casing 6+ times and they still have life, I've even reloaded some I've shot without a port buffer
it will launch it about 30 feet to the 4 o'clock position, the Buffer causes that to decrease to about 15 feet. without the buffer or deflector it hits the receiver just right to mangle it with a rather large dent.
