I'm all hyped up, I got some new brass and wanting to shoot my 243. The two books that I have for data are Lyman and Hornady, one calls for Federal 210 primers and the other Remington 9-1/2 large rifle. My local shooting supply is out of both. I did however bring home some CCI Benchrest primers. Have any of you folks used CCI BR primers and how did you adjust your data for them

Load um and shoot um

Hey Steve hope this helps you you are just fine we CCI primers thats all i use and like Bob said Load um and shoot um Steve get you a Lee first and second add. hey man CCI is the way to go in my exsperence. Good Luck

Just load them and use your normal load work up procedures. The differences between your rifle and the test rifle used to work up the load in the book will give much more variance than switching the primers will. That book load is only valid in the rifle they shot it in, not your rifle.

On a side note, I only use federal primers nowadays, I've had hangfires with CCI's and misfires with remingtons. Never had a problem with a federal.

I consider the CCI Br primers to be the best on the market.

Just use the same load data as for remington or federal primers, you wont have a problem if you dont start out with max loads, drop back a few grains and work up.

CCI BR primers work great with IMR 4350 and IMR 4831

all the talk about primers all the time is just that - talk. In 50 years of reloading I've loaded perhaps half a million round with every primer out here and they all go off. Sometimes, but very rarely there might be a difference, but they all go boom

Well said.....my experience also.....at least with rifle primers!

Count me as a third vote on the dependability and interchangability of primers. I've read of some dramatic events that were given (blamed) to be the primers but have never found that out first hand (knock on wood )

Primers vary a little in "force" or "heat" or whatever you want to call it, but in larger centerfire cartridges it is never enough to make a difference in safety. And in some brands "standard" primers will be hotter than other brands of "magnum" primers.

The biggest difference in "standard", "match", and "magnum" primers is in the price.

Besides, if you feel the need of a more powerful primer, simply pull the trigger harder. That'll do the trick.

As others have said, load 'em and shoot 'em.

Those CCI BR2 primers work great and I keep a couple thousand at all times. I don't know that you will notice any difference from a Federal or Rem but I can't change something that works so good.

Look at this

Wow, the Remington primers look like a rocket blast. I dont think that the CCI BR primers will cause much of a presure problem.

Primers can do a few things. They can either spew hot gas, hot particle, or hot particle and hot gas. The difference in the flashes is not unexpected or surprising.

Now that is a profound statement.

Or, from a slightly different perspective, quoting Li'l Abner, "As any fool can plainly see."

I used CCI's exclusively for 40 years. Now I use them and another brand (mostly because a friend gave me 7,000 of them). There are a few times you need/want a little more oomph (brisance) - then a magnum CCI or another hotter brand is warrented. But CCI's have been VERY consistant.

The Remington primer produced a lot of light. I’m not impressed with light shows or fire works displays. Just because a primer can produce a lot of light in an open-air environment don’t really say much about how hot it is in a closed cartridge environment.

GOOD POINT. If you look up the definition of brissance, there are several components to it. Do a google search -

Geez, I knew sooner or later one of you guys were gonna use the briesence word.
All I know is when I pull the trigger, my cci primer goes pop, the powder goes bang, and the bullet goes somewhere within 8 or 14" of where I was aiming.
Knock on wood, over the many years I've reloaded, I've probably used every major brand of primer (inter-changably among type I might add) and cannot recall a failure to go pop.

I brought it up because I've pulled the trigger and the primer fired, but did not ignite the powder - it was just crusted all together. Have done it maybe three times over the years and always with stick powder (not ball nor flake). A hotter (more brissance) primer would have cut through the graphite coating on the powder and the powder would have gone bang. It may also be an explanation for variance between shots - more consistant ignition.

You know come to think of it I have never had a hang fire with my hand loaded ammo, however I have had many with factory ammo over my life time and that is one of the reasons started loading.

O by the way I got a brick of Rem 9-1/2 primers a few months ago and several in each box of 100 have been crushed on the side like happens when you get in a hurry with a hand priming tool. have any of youse guyes seen that before?

I've used the CCI BR primers in a 300 Winny and they seem to be working just fine. I don't know what the difference is from the standard, maybe a little more consistent or just a little more expensive?

Their intention is that they be more consistant in manufacture compared to the run of the mill. From someone who visited them, he said they picked the operator who was most consistant to make them.

trk pretty much nailed it on the head for benchrest or match primers. Here's what CCI said about theirs from there own website:

CCI® BENCHREST RIFLE PRIMERS

In benchrest competition, there’s no such thing as a group that’s “too small.†Everything has to be tuned to the highest degree to produce match-winning results. That’s why we make CCI Benchrest primers. Only our most experienced skilled personnel put the priming mix in the cups, so you get the same flame, shot after shot. We also use specially selected cups and anvils for added consistency. An independent researcher identified the use of CCI Benchrest primers as one of two factors that were the most significant contributors to tiny groups. We can’t add much to that!

So we see, as trk said, more experienced personel assembling them, but CCI said the components are or better quality also.
