Great thread...my little contribution-
I once mistakenly used pistol primers for handloads, When I discovered this anomaly prior to shooting, I went forward anyways...I just geared up and tried it.
I found about 30% just misfired, and the balance pierced the primer- but discharged
These were fairly stout .270 wcf loads.
I purchased a shrink wrapped package of CCI large rifle primers , it had a pistol primers within it
Oops, but oh well ...and now I can pass this info along.
Don't bother to try this yourself.
Happy New Year , folks
