Magnum primers in non magnum loads

Since primers are so hard to come by right now and I am in the process of loading several thousand 9mm rounds. I was wondering if any one has ever had problems using magnum pistol primers in standard loads for 9mm.
I have several thousand magnum primers and don’t load 357's any more so this way I can use them up.
I know that I will have to rework my loads.
Thanks

As long as your loads are not maximum, you should be ok. Load a few and check them.

All that I have used for years in all my loads, is magnum primers. that way I can load anything I shoot & only buy one primer & load hot or mild loads. with a mag primer & light load, I just back off of the powder charge. never had any problems.

I agree with bogman....I use magnum in all my pistol/revolver loads. I only load Unique and Blue Dot in .38-.357-.44 mag and .45 auto....none of which calls for mag primers.

Blue Dot

Yeah and you may be headed for a crash too!

Just remind me not to go to the range with you when you shoot those Blue Dot loads, especially if the temperature is around freezing of less.

Listen, a recipe is a complete listing of components to get a specific load. Primer, case, bullet, powder type and weight, overall length, crimp type are all a part of the equation. To approach it like "this is no big deal because I have done it for years" is ignorant to say the least. Then to put it on a public forum without those details is sinister if you ask me.

The truth is yes, they can be used. There are some powders and situations that warrant close consideration before doing so. One of them is POWDER TYPE. Blue Dot is notorious for having pressure spikes when it gets cold. Couple that with a magnum primer and your favorite load that wasn't worked up correctly and "wha-la" you have pieces of metal sticking out of body parts that really don't need them to function!

Use caution, start over with your load development, minimum load, have a chronograph, and just in case you don't have any, bring a friend that has some common sense!

I'd be extremely reluctant to use magnum primers in 9mm. That itty-bitty case doesn't leave room for errors.

See if you can trade off some primers with someone else.

Why don't you figure out what powder and bullet you are going to use. Then contact the powder maker and see what they say about using magnum primers with that powder and bullet in 9mm?
