Normally cratered\pierced primers which is what you pic shows are caused by firing pin bolt fit. Flat, primers actually blown out of the case are headspace, or presser issues. With small rifle primers you have the additional issue of some primers designed for lower pressure i.e. CCI 400 or Rem 6 1/2. Bushing the firing pin and or switching to CCi450's or Rem 7 1/2 will cure most issues. With factory loads Bushing the firing pin is your best option.
