large rifle primers in 300wsm.
I Like everyone I have been unable to get any large rifle magnum primers lately. My question is has anyone ever used large rifle primers in the 300wsm? I was able to bum some off of a friend and need to go shooting but have been cautioned against using them. Something about pressure spikes.
FYI I will be loading 53.5g H4895 with a 165gr AB.
