Match primers?

[.Dirty-.30]

My shop didn't have any small rifle primers, but did have Match small rifle primers. I am continuing to test different loads in my Hornet with Lil'gun, are these any hotter than regular?

[Iowa Fox]

I think the match primers are a little hot for the small Hornet case with Lil Gun. Most guys are getting the best accuracy with Rem 6 1/2 or small pistol. Also the Lee Collet neck sizer and factory crimp die do very well relaoding the Hornet.

Typically No,
They're just supposed to have better/more presice components and be more consistant. You pay extra for tighter Quality Control oversight.
What the name brand.?

[Lloyd Smale]

not unless there match magnums.

I do notice a difference with Federal GM match primers, both in my .308 and my 7mm Rem Mag. Not so much in my 30/06 A.I. though...

There was a program on one of the shooting shows that showed all one would want to know about primers. They showed CCI  being made and noted that BR (their match primers) were only made by operators that had a record of very consistant production. The measure of quality is noted in the standard deviation of rounds loaded with a primer.

I called CCI about this a few years back and got Shootalls answer. Apparently there is no difference between the two except which machine they come off of. Other brands I couldn't say but that's how CCI does it.

These are Federal Match $4.59 per 100 at my local gunstore. They had nothing else left, so I am sampling some. I have tried pistol primers from CCI in my Hornet and get a pierced primer about 1 out of every 3 rounds, I think I have read height wise they a a fraction taller and my Topper barrel is on a shotgun frame with a larger size firing pin, so they aren't getting along. But the small rifle primers have worked without any trouble for many many hundreds of rounds so far. When and if I change frames I will again sample the small pistol primers.  Thanks for the responses!   .DT

So be safe reduce your load by 10% load a couple and try them then work up until you get what you want.

Small magnum rifle primers are not "hotter". They have thicker cups and that is the reason they are"magnum" primers.

[SHOOTALL]

I think I will disagree with that in all cases as they have a hotter flame needed with some powders in colder weather in some brands. But it is true they are thicker also there is less room for compound in the magnum cup so it would seem there is a different compound used. Hey different brands are hotter than one or the other.  If you are looking for thicker cups then go to CCI # 41 primers they have the thickest cups.They are made for military style fireing systems with no return spring that when the bolt is released it often times will leave a dent in the primer as the bolt closes and fireing pin goes forward as there is nothing to retain it. It also depends on brand of primers as to thickness of cup. There have been articles written stating  federal made very sensitive (thin cup) primers to test weapons for slam fire in cases where weapons were used in crimes and tested to see if they would fire more than once with each pull of the trigger.  .

Let's cut to the chase here Gents where it comes to "Magnum" primers vrs "Standard".
 
"Magnum" primers are not "Hotter",  in that the temprature of the flame being higher than the other primer of the same maker.
Magnum primers actually use a different (or more of) priming compound that contains a higher metal content like aluminum that throws a the flame farther into the case to ignite the powder along the full length of the charge.
OK,OK,, to stop any argument that may come forth about temp there may be some minor change,, but it's a good idea to think about the "Volume" of the magnum primer brisance instead of temp being the issue of the differance.
 
Every primer maker, Rem, Win, Fed,,,ect has it's own prioritized primer mix that they use thus the differance in "brisance" of each makers primer
