Firing pin hole size is a common thread on most any small rifle primer thread. The is in fact a small industry dedicated to correcting this issue. Having said that it does seem that ammo manufacturers would know this and only use the harder/thicker cup primers in any small primer ammo that approaches 54k pressures. I know you are not a reloader so don't know if this is any help or not.
