Couple of videos on YouTube on this topic, due to the current primer shortage. Bolt Action Reloading did one. He was demonstrating that it was not safe. All of the SPP that he tried in a minimum load 6.5CM had pierced primers. About halfway up the ladder with SPP magnum primers the primer was pierced. He referenced some other videos on the topic, but I didn't watch those.How does one tell what primers are in those reloads?
I tried an experiment with 2400 and small pistol and small pistol magnums, The same load of 2400 with magnum primers showed signs of over pressure while the standard primed shot just fine.
During a primer drought back in the 1990s I played with the idea of loading small rifle primers for 357MAG ammo, but thought better and did not. Small rifle primers are the same dimensionally as small pistol.
The collet type pullers will usually destroy lead bullets---get a kinetic oneDo I want a collet type or impact type and how does it know the type of bullet, both contour and diameter?
Can't even begin to count how many reloads that I've shot over the decades for several different calibers that other people have made.
Okay, the bullets will be pulled and the powder dumped. Not going to risk it.
The answer is then that a .38 Special inappropriately loaded CAN damage a .357 Magnum.
This seems contrary to the general consensus of this thread.
