A few years ago there were some bad Winchester primers out there. Some made their way out to Australia as well. However, I only ever heard it was some batches of large rifle primers. Were the small rifle primers affected?

Also, Winchester standard primers are/were considered the hottest of the primers. Does this also include the small rifle primers?

I'm looking to prime some 6.5x47 cases with small rifle primers. I have steered clear of Winchester since the bad runs and bought CCI large primers instead. I have Rem 7 1/2 but wondering if the Winchester small primers may give better ignition in cold temperatures (0 degrees celsius and below).
