Primer Opinons?
- Thread starter Brux
- Start date
I’ve read only differences between 210 and 210m is the m is assembled by someone who has been making primers for x amount of time. I have never seen the difference when testing them across my labrabar. My experience other may have seen something
As previously posted, the only real difference between 210M's and 210's is the experienced employee making them, which means one can or should expect the 210M's to be more consistent. I've got both and the recent batch I have of 210's have been as good as my 210M's. The same goes between 200's and BR2's. There IS a difference between Federal and the CCI primers, so you're most likely will see as substantial velocity difference between these two. Since you're shooting 210M's, you shouldn't really see any difference by going with your 210's except you might find a little inconsistency, so stick to the 210M's when competing.
These are some Federal GM215M primers from the latest batch I purchased. I have seen the same irregular fill in their non magnum LE match primers. If this is what an experienced worker does I’d hate to see what the acceptable standard is for normal workers.

The reliability of primers is 99.9997%, statistically you would hit a bad primer once every 300,000 rounds. What does that mean? I have no idea other than whoever is making the primer, new guy or salty veteran, the primer works. I'm personally more concerned about consistent depth of the primer (Primal Rights) then the "M". That said, I use both interchangeably and have never noticed any difference.
I've shot all of the ones that you listed and honestly I have seen no difference between them. For the cost difference, it would be nice to see an improvement!
I just did a head to head with 210M vs BR2 in my pet 130gr 6.5CR load. The BR2 resulted in slower average velocity by 15FPS. SD's and ES's were the same
+1 but with 205m. I also have MUCH more reliable ignition with federal over cci in my 6bra I honestly don’t think I’ve had one fail, I’d have at least 1 every outing with br4’s
I see similar with BR2s in my 300. Slightly slower than Federal. I did, however, find them to be slightly more consistent. It's what I use now, as I don't need the speed.
I've been using CCI #400s small rifle primers for .223 and 6.5 CM. Haven't had problem with igniting all the powder and velocities are pretty consistent.
