Large Pistol Primer Magnum or Match

Hello,

I have always used Federal Match primers but cannot find any. Anyone try a Federal Magnum in a .44 or 45acp?

Thanks...Seedsntrees

What powder? Is there some reason you can’t just use standard Large Pistol Primers? The Magnum primers will be hotter, so you will need to reduce your powder charge by a few % to allow for that. Most people use Magnum primers with large charges of hard to light (slow burning) powders, but I for one have never really seen the need for them?
Why did you feel the need for Match primers?

just shot the match for years...running out. I agree with your comments, slow burn could use help. Never needed a magnum, just can not find anything other than magnum. Thanks again...Mark

I’ve never used Match Primers for anything but my single shot bench gun for Schuetzen matches. If you’re shooting normal handgun loads with your 44 and 45, I can’t imagine being able to tell the difference between Match and Standard. If all you can find are Magnum Primers, just drop back to your starting loads or perhaps a couple of % less and have at it.

YES have used mag primers. you just need to cut your powder back some and work back up, these primers are hotter. If you know your FPS you can coronagraph and work back up to that speed? No difference between reg primers and match, match primers are just supposed to be more consistent, and just cost more.

I load pretty much in the middle of recommended minimum and maximum and honestly have never noticed any difference between standard primers and magnum primers. I normally buy only standard, but when the only vendor at a gun show has just one brick of large pistol magnum primers, and nothing else, they come home with me.

With the component shortages nowadays, I buy whatever I can get.

I AGREE! Shoot whatever you can find and make adjustments from what you are using...HANDLOADING

In .44Mag that's what they normally call for. 44Special shouldn't be a problem with reduced powder.
If your firing pin strike in the .45 will set them off, reduce the powder and maybe work back up.
When it was all I had-
I've loaded a bunch of 9mm and .38Spec. with Magnum primers doing that without any issues.
Being thicker, your fired primer will probably show less of a pressure sign. But that's OK.

I use Federal magnum LP primers in both my 45 acp and 44-40 revolver. Why? because both guns are new to me this year and the only LP primers I could find at a decent price were Federal LP magnum. All my load development was based on them. My problem is going to be the reverse-- re-developing my loads when I can get the right primers.

Match primers are a higher grade of standard primers made by senior personnel. No guarantee that person had a good day.

CCI Magnum primers are hotter, Federal Magnum may just be a thicker cup. Primer manufacturers make No useful information available.

I looked at my spreadsheet and I tested Federal 150 against Federal 155 Magnum Match and the Federal 155 Magnum Primers averaged 6 fps faster in the 900 fps range. 20 shots of each. Just batch to batch variation, the spread was bigger than that.
