I've never had ignition problems with winchester small pistol primers..... but... I'd be very uneasy in moving to a magnum primer in it's place for something like 9mm. Others have mentioned the fast burning powders leading to pressure spikes, and the fact that a magnum primer prolly excasterbates this problem. I'd concur in a bookworm fashion (lacking personal experience).
Rather than moving to a magnum primer, I'd simply attempt another brand of pistol primers, restarting load data back at the starting recommendations and inching up as usual.
Without any kind of pressure measuring tool, I would be way too chicken to attempt a magnum primer.... especially with fast burning powders.
Stay Safe!

I traded the magnum primers for the small pistols in CCI. I'll feel better about then next 1K rounds.
I've read the metal is thicker is all, and CCI engineers say a 5% decrease in powder will more than compensate . This would make sense with the 4 rounds my gun dented hard and did not set off the primer. a 2nd hit set them off except 1.
Not sure about you guys, but I get a 5% deviation in my powder measurements using a scoop. I really dont think it matters except near or over max loads, where it becomes the needle that breaks the camels back type thing. But of course we want to be safe but just know during a shortage magnum primers are easily had.

However lots of people use them and I have about 1K round through 3 guns so I feel pretty good about them. I did fire off a box of federal brand cheap stuff today from walmart and it produces noticibly more recoil. Not sure if there is a relationship between recoil and pressure but it sure did seem a lot stiffer and louder.
I've just always used CCI primers and the small pistol non magnum are hard to find right now. I can get winchester, but the main reason I dont like them is because they arent silver.... They are brass colored.
Hoping this week to get anothe 2K in primers the right size, and 2K in berrys. Wish me luck on that. Wont have the $$ until this week and the supplies are drying up fast.
