Primers backed out is a sign of low pressure. Primer is developing more pressure than powder charge and on firing primer will drive cartridge deeper into chamber. Bolt face supports primer and case is blown forward. Getting rid of live primers in empty cases by firing in chamber will back out primers too, and will set shoulders back slightly.
