I'd actually experienced a micro "hang fire" with a moderately reduced load of AA9 and Standard LPP's.
ES's were pretty extreme for handgun ammo as well.
The Magnum primers sorted it out. Live and learn I guess.
Another thing I saw was that I use a note pad to write down my chrono readings and I had a lot more unburned powder kernels on it with standard primers. Definitely a noticeable amount. That and the chrono told me that magnum primers are the way to go. Groups at 15 yards were fine with both so ES and SD don't always mean a lot at pistol distance but the chrono numbers do tell a tale. I used to shoot a lot of 296 in magnum revolver loads and it's a magnum primer only powder. AA#9 is very similar and my experience makes me wonder why they say regular primers are recommended. I've seen no difference in pressure signs even at max loads so I guess their safety factor in their load data is sufficient.
Very little beats a nice model 58. Beautiful revolvers.

Support the entire Constitution, not just the parts you like.
Common sense is only right wing if you are too far to the left.
A pistol without a round chambered is an intricate paperweight.
Stop trying so hard to be offended.
That is one of the best looking M58s that I have ever seen.
Well thanks!
Very slick wheelgun. 41 mag was always an interesting round
