New Federal Gold Metal Match Primers for ARs
- Thread starter big bear
- Start date
Remington ran Lake City Army Ammunition Plant from 1941 until 1985 and used their 7 1/2 and 9 1/2 primers during that time in 7.62 and 5.56 ammunition.
In 2001 ATK took over production at Lake City and decided to use primers with thicker cups and shorter anvils. I would ask what type primer is used in Canadian military ammunition. It seems to be a solution to a problem that doesn't exist and charge the government more to make ammunition.
Both the M14 and M16 rifles had their firing pins lightened during initial development testing to prevent slam fires. Meaning after all these years why do we need "special" primers.
I use Remington primers in my M1 Garand and AR15 rifles and never had any problems. The biggest chance of a slam fire is when loading a single round in the M14 and AR15 rifles without the magazine in the rifle to slow down bolt velocity. And this is why the firing pins were lightened after initial field testing to prevent these type slam fires.
If you want extra peace of mind then go ahead and buy these primers, but many wars were fought without them and I do not see any need for them now.

Many wars were fought with black powder, swords, catapults and trebuchets too. Heck, in 525BC, the persians easily defeated the egyptians at Pelusium by using cats as shields.
So yeah, of course, that means those primers are a gimmick to charge you more.

Anybody tried these?
Where did you find them?
Thoughts on their utility in Lapua small primer 308 and 6.5 Creedmoor brass?
I would also never use Lapua brass in rifles that throw perfectly good brass away and makes you go look for it.
I buy bulk once fired Lake City 5.56 and 7.62 brass because the cases are much cheaper and made tougher than commercial brass. And I don't cry if I loose a few of these Lake City cases.
The last rifle I bought was a Savage .308 and looked into buying some Peterson .308 match cases with small rifle primer pockets. I Googled the subject and the majority of responses said they had better results with large rifle primers.
Bottom line, the Lake City cases are more uniform than Remington and Winchester cases. And by weight sorting and with some prep work you end up with very good cases far cheaper than Lapua.

Lapua Reloading Brass 308 Winchester Palma Small Primer Pocket Box of 100 $80.99 plus shipping

Neither of the above sources can legally ship directly to Canada. Brass, bullets, powder, and primers are ITAR controlled goods. In fact NO U.S. supplier can ship these items (even so-called once-fired) to Canada without going through a very expensive and convoluted procedure dealing with a secondary licensed importer. The resulting cost makes Lapua brass a positive bargain in comparison. Lake City brass can occasionally be found mixed up with random other makes sold as once-fired range brass.
Again... really?
Look, people want a safer alternative when loading for their ARs. Fact is that with the primers that are available now folks are much more protected against slamfires that have occurred using 7 1/2 and 9 1/2 primers; period.
I do not see why every time primers for ARs come up you feel the need to post the same few paragraphs saying the same thing over and over again. Look, things improve, things get better and things undergo development for their specific purpose.
If you don't want to use them that's fine, but please stop dissuading shooters from taking a safer course when reloading for their ARs.
I will voice my opinion based on over 47 years of reloading, if you do not like my posting then do not read them.
And I base my opinion by loading a single round in my AR15 chambers without the mag in the rifle and letting the bolt slam home to test the primer.
The highest bolt velocity and highest firing pin inertia will occur during this test to see if the primer goes off.
It is recommended to use small rifle primers with a cup thickness of .025 with firearms with free floating firing pins.
And it is the people using the thinner primer cups that are having slam fires because they do not do any research on the subject.
And with the .308/7.62 you can use large rifle primers that have a cup thickness of .027. So why use .308 cases that use small rifle primers when standard cases use thicker large rifle primers.
And on top of this we didn't need special primers with the M1 Garand, M14 and M16 rifles until ATK got the contract at Lake City.
And it is CCI and Federal that are having slam fire problems with their thinner cup small rifle primers.
So tell me what type primers does the Canadian military use in their ammunition. If you find out the Canadian military specifications please let us know.
The best part about reloading is the person pulling the press handle decides how to do it. And if you are having slam fire problems then by all means switch to thicker and harder primers. And all I can tell you is I have never had a slam fire in any rifle I have with a free floating firing pin in over 47 years of reloading.

My intended use of such primers is to load for my AI/AT bolt rifle
My question was about using these primers to load small rifle primer Lapua 308 and 6.5 Creedmoor brass for my AI/AT bolt rifle. I don't reload for my AR15, bulk ammo is cheaper than my time. I guess I should have been more detailed in my questions.
thanks!

I tested the 205 MAR against CCI 450 and the 205M In the 6.5 Creedmoor. My little bit of testing was done with only one load
and all 3 shot pretty well the same for me at 400 meters with 10 shot groups. Not too scientific, but enough for my curiosity.

Don't mind bigped, he just keeps copy/pasting the same stuff that's usually unrelated to the OP's question.
To answer your question I haven't tried those federal, but so far my experience has been that primers don't really make a difference for me. If you're shooting bench rest competition (which I don't), you might have a different opinion. But then it'll be up to you to try every type of primer in your particular rifle.
There was a guy who weighted batches of primers on a fx120, and he found that more expensive primers like "gold match" and "bench rest" (CCI BR2 and BR4) had less variance in their weight than their normal counterparts like federal champion or CCI 200/400. Since both the 205M and the 205MAR are part of the same lineup, there's probably very little difference in the accuracy you'll achieve between both.
A LOT of what bigped posts is very good info, with excellent diagrams, etc, but yes, unfortunately at times it doesn't match up very well with the question asked. In this case the thread title is "New Federal Gold Metal Match Primers for ARs". Both .308 and 6.5CM AR's exist; maybe not in Canada, but yes, they do exist. On top of that the OP didn't say squat about it being for a bolt gun so his assumption about it being related to a discussion about ARs is valid.
